- Installing MemoPad & CheckMemo
- ==============================
-
- I assume that if you are reading this that you have already de-ARCed
- the MemoPad files. There should be a total of 7 files for this
- program set. As soon as you invoked this program, all the names
- were auto-magically expanded out, so you won't have to go through the
- usual hassle of EXECUTING the Execute.Me file that is usual in these
- cases. Why doesn't someone get around to providing an ARC utility
- which will automatically do this if it encounters a longer name?
-
- The CheckMemo utility will check whether any memo items have been
- entered for today's date. So, in order to do this automatically
- when the AMIGA is powered on, a `CheckMemo' command should be placed
- in your S:Startup-Sequence file, right after any additions or prompts
- which normally set the date. Next, place the CheckMemo and
- CheckMemo.info files in your C: directory or on one of the paths that
- you add to the command search list. That's all there is to the
- installation -- easy wasn't it. Note: you can also manually check
- the memo items simply by typing `CheckMemo' from CLI or by clicking
- on the CheckMemo icon. The latter operation may be tricky if both
- CheckMemo and CheckMemo.info are placed in the C: directory, unless
- you keep another copy at the top-level of the WorkBench disk or along
- with the MemoPad. If nothing happens except a disk access when you
- invoke CheckMemo, don't worry -- it just means that no memo items
- were found for today's date.
-
- The MemoPad utility, which creates the memo items read by CheckMemo,
- may be placed on any convenient working disk which would ordinarily
- be used during your work/play/recreation time with the AMIGA. Simply
- drag the icon over to your working disk, or from CLI, copy over both
- MemoPad and MemoPad.info to the working disk.
-
-
- MemoPad Operation
- =================
-
- MemoPad is a WorkBench utility which runs in a separate window on
- the WorkBench screen. It is capable of allowing you to generate memo
- items which are simply dated reminders of appointments, birthdays,
- holidays, or any message which can be held on five lines of text.
- When MemoPad is first invoked, it searches the S: device directory
- for a file called MEMOPAD.DAT. This file contains all the memo items
- which have been entered by yourself. Naturally, the first time it is
- invoked, MemoPad won't find this file and will attempt to create one.
- At this time, you may get a message indicating that the WorkBench
- disk is required or that you should unprotect the write tab.
-
- During start-up, one other file is accessed : MEMOPAD.CUS. This file
- contains user customization information which allows you to customize
- the MemoPad operation to your individual preferences via the
- CUSTOMIZE menu selection in MemoPad. If this file is not found,
- MemoPad makes some assumptions and gives you a 24-hour clock, a
- day-month-year date, and a plain MemoPad title. Naturally, you can
- customize all these parameters and the next time MemoPad is invoked,
- all your selections will be used. By the way, the same selections
- will also be used by CheckMemo.
-
- I felt that everyone would have WorkBench in their drive during
- startup, so this is where MemoPad normally assumes it will find your
- memo items. If you don't like these files on your WorkBench disk,
- then it is possible to reassign the S: device to some other disk. If
- you do this in the Startup-Sequence file, just before invoking
- CheckMemo, you will be prompted to insert whatever disk was assigned
- to the S: device.
-
-
- Other Nifty Things
- ==================
-
- MemoPad lets you specify repeated memo items which occur fairly
- regularly on a daily, weekly, monthly, or annual basis for a fixed
- length of time. To generate such a memo item, first you'll have to
- enable repeats by selecting one of the repeat choices in the REPEAT
- MEMO menu list. By default, repeats will be disabled as is shown by
- the checkmark in front of the "No Repeat" menu item. Choose one of
- the repeat options and use the NEXT or PREV buttons to get to the
- memo you wish to have repeated. Click on the DATE button, and use
- the Date Window controls to get to the starting date to be repeated.
- Click on the desired date. All repeated dates will now also be
- selected. Use the Date Window controls to check them if you don't
- believe it could be that easy. Click on the OK button to close the
- Date Window and accept the chosen date; otherwise, just click on
- the QUIT button to keep whatever date was originally on your memo
- item.
-
- The FIND button and the related menu item will let you find one memo
- out of the list of memo items which you have defined. Click on this
- button, use the Date Window controls to maneuver to the desired date,
- and click on the date to be found. Click on the OK button and the
- first memo item with this date will be located and displayed. This
- date search may be cancelled by clicking on the QUIT button. If the
- date is not found, a message saying this will be displayed in the
- Help Window. A trick, which may be used to find any memo item in
- a given month might be to select the daily repeat for a month before
- clicking on the Date button. Any date which is selected will now
- cause a search throughout the entire repeat range for any matching
- memo item dates.
-
- The Help Window is a context sensitive help feature which displays
- help messages as various buttons and/or menu selections are made.
-
- There is never any need to worry whether or not all your memo items
- have been saved to disk! MemoPad will automatically update the disk
- file, as soon as it notices that some memo item has been changed.
- Even if some other program should cause the AMIGA to crash in a
- shower of fireworks, you'll be secure in the knowledge that your
- memo items are safe.

- About the Modula-2 Source
- =========================
-
- Probably the first question anyone (especially `C' hackers) would ask
- is: Why use Modula-2? As a company, Computer Inspirations has a
- vested interest in the success of its products. Part of the measure
- of a successful product is the ease with which any product can be
- updated to meet new and anticipated needs of its users. We feel that
- Modula-2 provides such a vehicle through the use of modern software
- design principles such as object-oriented programming techniques and
- Dave Parnas' information hiding principles. In addition, Modula-2
- provides a more readable source file which, with the addition of
- suitable comments, can give software maintenance personnel greater
- productivity. Of course, `C' die-hards would argue, and justifiably
- so, that `C' also provides commenting facilities and does not have
- to be cryptic. We would agree with this in principle; unfortunately,
- in practice, the same people who thrive on the so-called `concise'
- representation possible using `C' will also shun the use of good
- commenting techniques. In the final analysis, with the proper
- tools (compiler, debugger, etc.), Modula-2 code can be just as
- compact and fast as `C' code -- without the need for brain-damaging
- syntax.
-
- We, as a company, provide the source code for MemoPad and CheckMemo
- primarily to give interested individuals the tools for programming
- the Amiga using the Intuition-based interface. Included in the
- source are many examples of gadget-based control, menu initialization
- and use, window creation and manipulation, and requester window use.
- Although bits and pieces of what we do are available in separate
- sources, we feel that having an example which unites all the working
- principles required to produce a full program is beneficial in its
- own right. As a final note, this program does not show the full
- benefits of the new software design principles since that was not its
- purpose. We do use comments and structured design principles. This
- program fails to make full use of the information-hiding metho-
- dologies in some places -- but it is better than a comparable `C'
- program in this respect. Our primary aim, of course, was to produce
- a program from which others could see how to work within an
- Intuition-based environment; and in this respect, we feel that we
- have succeeded.

- Acknowledgements
- ================
-
- As always, there are a bunch of people behind the scenes who must be
- thanked for their contributions, either direct or indirect, to a
- program such as this. Firstly, thanks to TDI for their Modula-2
- compiler, which may not be fastest or the best, but it certainly was
- the first. Secondly, thanks to all the people who have contributed
- public-domain programs to demonstrate Modula-2 concepts and give
- others source code examples upon which to build. In particular,
- thanks to Richie Bielak for his FastTextIO routines, used in this
- previewer. We also appreciate the artistic talents of Anna-Lise
- Scheel, Colour Consultant, for her work on MemoPad. Thanks also to
- all the Beta test sites (you know who you are) for their assistance
- and helpful comments. Thanks also to the people who brought us
- PowerWindows which was used as a starting point for the design of
- windows, gadgets, menus, and requesters used in both MemoPad and
- CheckMemo. Although, the Modula-2 extensions to this program are
- VERY buggy and have been given inadequate thought, the tool has been
- useful. Finally, thanks to the makers of the Amiga -- without whom
- none of this would have been possible.
-
-
- Bug Fixes
- =========
-
- Much as we hate to admit it, a few bugs crept into the V1.0 release
- of MemoPad and CheckMemo. Thanks to the people who pointed out the
- bugs (people tend to do that). All known bugs as listed below have
- been exterminated :
-
- Bug 1.0-1 The programs stomped over memory location 00000000
- while starting up and initializing the Date window.
- Although this bug didn't usually cause the programs
- to crash, sometimes, if another program depended on
- something in memory location 00000000, a crash could
- occur. As a matter of fact, if both MemoPad and
- CheckMemo were running together (yes, they can do
- that too), closing down one would cause the other
- one to crash the Amiga. In our defense, the bug
- was traced to a pointer to a pointer which the
- current V3.0a TDI Modula-2 compiler doesn't seem to
- handle very well. PowerWindows forced us to use
- the awkward pointer to a pointer syntax (they must
- be `C' programmers!), hence our memory stomping.
-
- Bug 1.0-2 To our shock, we discovered that the DOS date was
- in error by one day (at least during this leap year).
- It worked fine last year. ;-)
- A new algorithm is now being used.
