MASTERFILE PROFESSIONAL (M-PRO)www.masterfilepro.infoAn unofficial site for the Masterfile Professional (M-Pro) relational database program Sections on this page
This site started: 25th May 2007. Last updated: 7th May 2011. Masterfile Professional - SummaryMASTERFILE Professional ("M-Pro") is a flexible general-purpose, programmable, relational database and text file manager for use on
virtually any PC. Masterfile Professional nowM-Pro has keen users who find it very useful and full of thoughtful features. There are many other database programs but few as
satisfying. The fact that it is a DOS program must put off many. While being a DOS program can cause some problems (depending mainly on the
computer and printer used), they can be largely overcome. Masterfile Professional User Group (MPUG)It is proposed here that the Masterfile Professional User Group (MPUG) be revived, on an informal basis, for the mutual benefit of the
program's users. If you use M-Pro please register your interest. There is no commitment and no subscription.

M-PRO can manage these in much the same way as can other text editors. An Indexed Document file, or IDF, is one in which many documents can be maintained, each indexed with a name of up to 30 characters. There are many advantages to storing documents in an IDF. They are efficient on disk storage, they are easy to recognise, and they can be manipulated in groups. Although to DOS an IDF is a single file, in some respects it can be thought of as many files (documents) accessed through an index analogous to a disk directory. An IDF offers a very tidy way of storing and maintaining texts. Note: Junior/budget edition of M-PRO does not allow IDFs. A Data file is a structured file containing information organised into records and fields which can be searched and displayed in many different ways. Each data file can have several indexes, each presenting records in a particular order, and allowing relational linkage to other data files. Each data file has an associated service file, which holds all the data file's specifications. When a data file or document is being presented or worked on, we call it a task. M-PRO allows several tasks to be open at the same time, and the user can switch effortlessly between tasks. Tasks can be presented full-screen or in a "window". A clipboard systems permits text to be copied from one task, document, record or field to another. M-PRO has an adjourn option which allows the program to be shut down in such a way that it will automatically warm-start the next time it is used. Warm-start reinstates all tasks which were open at the last adjournment, and resumes at the adjourned position. (Exception: with the network version, shared data file tasks are not always warm-started since other users may have changed the file meanwhile.) Task-switching and adjourn/warm-start allow the user to leave one job, do another, and then return to the first job (or any other) where it was left off, without the need to close or open or re-position within files. You can be writing a letter and in mid-paragraph find a need to refer to a data file before continuing with the letter. With M-PRO this is easy. You open the data file and work on it, then touch a key to return to the letter with the cursor flashing right where you left it. If you have left the data file open, another key-press takes you back to it. You can "lift" information from one task and copy it into another using the clipboard. Just two key-presses adjourns your session, to be resumed at the next run of M-PRO when it will warm-start automatically. At the end of your work session, rather than closing down all tasks and quitting M-PRO, you may find it more convenient just to adjourn. Re-booting and disk re-organisation will not hinder the next warm-start. Data File Concepts A data file is designed by numbering and naming its constituent fields in a data specification document. This document can include validation rules, presentation rules, pop-up data menus, and is interpreted dynamically. This means that there is no compilation phase and changes may be made and tested in seconds. A data file is presented and operated through one or more formats, which are documents describing which fields to show, where and how to show them, as well as headings, narratives, line-drawing. As with the data specifications, formats require no compilation and they are instantly and easily modified and tested. Formats not only display the data, they are also used for data entry and data modification, and for printed output. Over sixty formats can be built into a file, and they may be modified at any time. Two of them, which we call system formats, are built automatically. Even greater power and flexibility is available through M-PRO's data language, called DPL. Using DPL a sequence of processing steps (called a program) can be written to calculate and display derived information. DPL also provides the means to retrieve data from other files to augment the immediate file. Files thus connected are said to be relational. DPL is written directly into a format in order to display relational and derived data. It may also be written into other parts of the service file from where it can be used to perform other processing both automatically and on demand. There is no visible compilation stage and the change/test cycle is a matter of seconds. The data proper is stored in a file which has a relatively simple and robust design. Indexes are used to sequence the records and are maintained in separate files which can be erased and re-generated at will. The secret to M-PRO's file design flexibility is the concept of the service file. Every data file has an associated service file in which reside all the specifications, formats, programs, and other user-edited effects. A service file has the same structure as an IDF; it can even be accessed like an IDF although this is not usually necessary. Extended DPL For advanced applications, DPL programs can be written in an Extended or External form, called EDPL. EDPL programs allow M-PRO to be run in a highly tailored manner, and are written and compiled independently of any data files. One EDPL program can be made resident, which means that it can be invoked on demand to call other programs or to open or switch to other files/tasks. Note: Junior/budget edition of M-PRO does not allow EDPL. Other Main Concepts Central to all M-PRO's text processing is its editor, used for all data entry and text handling. The editor offers most of the expected WP functions, including a spell-checker (except budget/junior edition of M-PRO). The spelling dictionary includes place names, common UK surnames, forenames, and abbreviations, and may be updated in use with the user's specialised terms. A central printer driver serves all files for the purpose of special effects such as underline, double-strike etc. Several printer drivers are provided, addressing the main classes of printer: matrix, ink-jet, and laser. The user may adapt these and create other drivers. The program allows three levels of pop-up help. There is the on-line manual [from which most of this is taken]. Two other levels are set up and maintained by the application designer or the user. One is for global use, i.e. task-independent; the other is specific to a data file and is accessible while working in that task. A sequence of key-strokes can be stored as a macro ready for re-use. You may set up both global macros and file-specific macros. Most macros will be file-specific. General Discussion M-PRO is primarily menu-driven. Most of the time there is either a menu on screen, or a list of topics from which a menu may be summoned. Most of the standard menus also offer further explanatory notes (at the bottom of the screen) coupled to the menu bar. Whilst in theory M-PRO could have designed so that every function is invoked from a menu, it would have been cumbersome to use this way. Instead, most of the often-used data and editing functions are summoned using direct controls which must therefore be learned by the user. For example, to delete a line of text while using the editor, we use Of course, the on-line manual tells you everything you need to know, so the only control key you really must commit to memory at the outset is There are opportunities for the designer to build choices into the system, such as display styles, search patterns, and functional macros. In all such cases, M-PRO provides the means of giving a descriptive label to every option. Thus the burden on the user's memory is minimised since the system always presents a menu of these descriptions. While you are viewing your data the screen is kept reasonably uncluttered. One does not want the screen to be over-crowded with unimportant information, but one does expect certain reminders on screen, such as the date and time (at top) and something telling you where the cursor or the highlight bar is (at bottom). In addition, since M-PRO allows several tasks to be open at a time, one needs to know what task or file one is looking at (task caption). However, even these screen effects can be switched off if you prefer. History of MasterfileThe MASTERFILE filing system first appeared in 1982, on computers built around the Z80 micro-processor. The first "PC" edition for
IBM-compatibles appeared in 1987. All editions were menu-driven and offered variable-length data and multiple user-designed data
presentations. Most editions allowed data files to link relationally. In 1989 the third PC edition introduced a text processing
option. Tips for M-Pro usersThis section, on a separate page, includes information on the difference between the character sets used by DOS and
Windows, alternative ways of printing from M-Pro, and a little about creating Web pages. Database solutionsVarious ready-made database solutions or structures, using M-Pro, have been offered by Campbell Systems and by others. Here are some of
them (there might well be others). The M-PRO DIARY The M-PRO DIARY is a compiled EDPL application which provides a way to keep track of memos, appointments, birthdays and other anniversaries, presented as a variable-depth day-by-day diary. You can make it open automatically when M-PRO is run for the first time each day, and at any time when M-PRO is running at the touch of two keys. It could not be simpler to operate. The entire display can be colour-customised during use, so there is no need to get involved with the DPL source code. The source is provided, however, for your interest. Features include: - Up to 10 lines of text per memo/appointment - Smooth vertical scrolling through variable-depth entries - Go to any day, any month, any year - Find anything, find next/previous, find by tick char - Print day, week, month, birthdays/anniversaries, found texts - Customise all colours - Optional dividers between events in a day (yes in fig.) - Optional week nos. and day nos. (yes in fig.) - Insert memo, appointment, birthday, anniversary - Alter memo or appointment - Nudge memo/appt up or down within day - Move memo or appointment to another day - Replicate memo or appointment daily, weekly, monthly etc. - Highlight memo or appointment in any colour - Tick or un-tick memo or appointment - Delete any entry - Pop-up calendar - Pop-up help - Post memo or appointment into M-PRO Alarm-clock list. - Pop-up memo sheet for up to 60 lines of "misc" text. - Pop-up address-book, which overlays the diary thus : - The address-book can be called and used independently of the diary system. It has its own colour customiser and pop-up help. Text can be transferred from diary to address-book and vice versa. Campbell Systems' DIARY was priced at £20 + VAT (UK, EEC) or £20 + £2 P&P (Other countries). M-PRO DPL Tutor The way to get the most out of M-PRO is to make use of the built-in language, DPL. When M-PRO was first launched, DPL offered sixty or so statement types. Now, DPL boasts nearly 200 statements and many of the original statements have been improved. Also, DPL can now be written outside the data file environment, to control tasks and files, and to process files directly. The author's own DIARY system is written in DPL which processes its data file without you ever needing to see the file in the traditional or "native" manner. Whilst DPL is fully documented in the OLM, some M-PRO users remain uncertain about what DPL can do or they lack the confidence to "give it a go". The DPL tutor is an IDF containing 26 lessons, each in the form of a document to be read on screen. The lessons include in total about 260 DPL programs, each of which can be run on the spot! All you have to do is to steer the cursor to a program and press Campbell Systems' DPL TUTOR was priced at £15 + VAT (UK, EEC) or £15 + £2 P&P (Other countries). CONTACTS Database Here is the author's description: As an M-PRO user, you will almost certainly have a data file listing your business and/or social contacts. After we had made one for our own use at Campbell Systems, visitors expressed how handy it looked and so we decided to make it available to all MPRO users. Our CONTACTS Database holds not only the obvious data such as name, company, address, telephone, fax nos., but other fields by which to categorise : status, keywords, type of business, reference, markers. Use them any way you wish, even change their captions. A major feature is a large scrollable "Notes/Info" field into which you can place up to about 65 lines of text. Not only can you edit the notes/info as a whole, you can also append a date-stamped entry. The search functions are pre-programmed for most fields, and you can also do global searches and single-key un-select. All colours can be individually adjusted to taste, without having to tackle the source code of the program. CONTACTS is supplied with the DPL source code, as well as in compiled form, so you are welcome to inspect our work and adapt it. Campbell Systems' CONTACTS was priced at £15 + VAT (UK, EEC) or £15 + £2 P&P (Other countries). BANK Account Manager Here is the author's description: BANK is designed for use by private individuals and small traders. It models one or more bank accounts, providing a means of checking statements, displaying current balance, and displaying useful reports and bar-charts. The main account view resembles a bank statement, but with some extra columns - such as category, folio, goods, VAT, etc. Up to ten accounts can be managed. Each account can be customised in respect of whether categories and certain business functions, etc. are required. Each account can operate up to one hundred automatic transactions, such as regular standing orders, direct debits, transfers. An automatic transaction can be monthly, quarterly, six-monthly, or annual, and is generated as soon as its month is reached. One of the display columns shows a tick for reconciled items, i.e. those matched with the bank statement. Each account therefore can show not only the balance as per statement, it also gives the balance in respect of transactions not yet shown on the statement. It is like having an instant statement on demand, without having to visit the bank or use the 'phone. A useful feature is that expenditures can be entered which are not real withdrawals. For example, when a business expense is paid using a personal credit card, it can be recorded in a current account as a withdrawal without affecting the balance. The payment method tells the system that it is a "dummy" transaction. Why is this useful ? Because such items still contribute to searches and analysis. The account database exists not just to model the current account, it also serves to model the business outgoings. Money can be transferred from one account to another using a single transaction. Both deposits and withdrawals can be categorised for the purpose of later analysis. The user defines the categories, each comprising a two-character code and a short descriptive text. We wrote BANK to be used as a "stand-alone" system, complete with its own cut-down M-PRO and OLM-style manual. You can use it that way, or you can instead call it from your resident or EDPL program if you prefer to stay in your own M-PRO. Campbell Systems' BANK was priced at £25 + VAT (UK, EEC) or £25 + £2 P&P (Other countries). AvianStore A database by Wes Halton for bird watchers.
