- HOW2HACK.MSG 11/15/81 Tom McCormick
-
- I'd like to suggest some guidelines for making changes to
- public domain programs on RCPM's. I have spent a fair amount
- of time on a couple dozen RCPM's around the country in the last
- 12 months.
-
- I'd like to see some of the leading contributors write a
- .DOC file or two that could be permanently enlarged and refined
- to become an outline of good practices for the RCPM scene.
-
- Ward and Ben and Kelly and others have been writing messages
- and comments lately about the horrible job some hackers do to
- good programs. I'm suggesting that we list some of the good
- practices and require (clearing house), or encourage them.
-
- 1. The change should produce some benefit with BROAD
- appeal. It should be TESTED for a few weeks prior
- to submission. Dry running it on a friend or two
- might also uncover something before hundreds of
- people download it, only to have to download an
- immediate "fix" or "improvement" a few days later!
-
- 2. The source should indicate the author, version number,
- as of date, and modifications since last version.
- The purpose of the program should be immediately stated.
- The comments should be in reverse chronological order,
- and should be at the very front of the source so that
- the 80 line typesq limit won't put 'em out of reach.
-
- 3. The program should sign-on indicating the version #.
-
- 4. If the program requires parameters passed to it, it
- would be preferable to display a help menu or prompt
- rather rather than abort, or exit the program. The
- reason for this is the growing use of menu programs;
- they require a "second chance" to pass the parameters.
-
- 5. A separate .DOC file is preferable. It should contain
- the identical program name where possible, so that it
- is clear what it belongs to.
-
- 6. Program names of six characters or less will allow for
- revision/version numbers to be appended later.
-
- 7. If 2 or more programs are related, they should begin
- with a common set of characters to force them to sort
- together in directory listings.
-
- RBBENT27.BAS and RBBMIN27.BAS
- is preferable to
- FLS SQ USQ and CHANGES
-
- 8. Give some thought (and effort) to avoiding use of words
- or terms already used on non-CP/M systems. Programs have
- been known to migrate, and the growing use of C and other
- portable high level languages will only increase this.
- Ask for help from SYSOPs or other users before setting
- your pet name in concrete.
-
- 9. DO NOT MAKE COSMETIC CHANGES to programs you send back
- up to RCPMs. The confusion far outweighs the "beauty".
- Users do better with consistency than with constant change.
-
- 10. Use DB's rather than equates for hardware dependant code
- so that it can be readily patched with DDT, etc. MODEM7
- is a nice example to follow, and all the bytes are in a
- contiguous string right up front. Nice.
-
- 11. If you submit .BAS files to RCPMs, do that in ASCII so
- they can be "TYPED". Nice to know if they're CBASIC or
- MBASIC, or what.
-
- 12. If a program is hardware dependant (Vector graphics), or
- release dependant (ver 1.4 only?), or language dependant
- (M80 but not MAC), this should be indicated in the filename,
- or in the .DOC file right up front.

- Well, I'll quit now. Give everybody else a chance to hack
- this up too. Have at it.
