[comp.sys.mac] compatibility

I have this mental image of Chris Espinosa sitting around with a bunch of
people at Apple and saying, "OK, what we need is a program that does something
useful but is old enough that the authors weren't trying to second-guess
the ROMs yet."

And you know, there's a moral to that story...

C combines the flexibility of assembler with the power of assembler.

Something that never ceases to amaze me is that I still use an OLD
version of Microsoft File (created Jan. 4, 1985) for some old inventory
databases.  Not only does it work perfectly on my current system (a IIcx
with System 6.0.3 and all sorts of INITs and cdev's) but it uses the
full 13" screen size flawlessly!  Sounds like Microsoft followed the
rules, even those that didn't exist back then.

I think I still have my original copy of Multiplan around somewhere.  I
guess it must still be worth something. :-)

You must not have very many fonts.  I still use MS-File for some old
databases, and when I went to make a LaserWriter printout of one and tried
to change the fonts to laser fonts, I discovered that the font list (a
scrolling list in a dialog box) consisted of some small number of real
fonts and a lot of BLANK entries!  The real fonts were apparently randomly
chosen (probably the ones with the lowest IDs).  I managed to find (blank) 
Times and (blank) Helvetica by click-and-hope, but it was a real pain.

Don't you know by now that Microsoft NEVER follows the rules?

After all the problems of _Launch crashing on Pluses, IIci's, and
occationally on IIcx's, I understand why few people write Macintosh
software.

To insure compatibility with all Macs, I need one of every type of Mac
and every version of System software Apple has ever produced.  What
happened to the great Macintosh ideal of compatibility across machines. 
I follow all the guidelines when I write my software, but all that
insures me is that it'll hopefully run on MY OWN machine when System x+1
is released.

To all those people who crashed their Macs running _Launch: I guarantee
that it'll run on a Mac IIx w/ 2meg, and no useful INITs.  That's my
setup.

  The problem with Launch appears to be with faulty code, not
compatibility across all Macs.  It's true that testing a program
on several models can help catch bugs, but  this is clearly not
a prerequisite for functional code.

  The assertion that "few people write MacIntosh software" seems like
a pretty arrogant one to me (aside from being highly contentious).
