     Let's hark back to the good old days.  You know, the Volume I, Issue 3
supplement, back when the "March" supplement came out in "June".

     In that developer's supplement, they supplied a program and DA called
"JumpStart".  As mentioned in the _old_ Tech Note 57, you could arrange your
resource fork so that (1) the preloaded resources were contiguous in the file,
and (2) the resource map is at the beginning of the file (this implies that
the resource fork is read-only).  If you did this stuff, your application's
launch time would be substantially improved.
     Unfortunately, JumpStart doesn't work too well with System 6.0.3 on my
Mac IIcx.

     I sent a message to Tech Support on AppleLink a few weeks ago, asking
about the status of JumpStart and whether doing these things was still kosher,
but they never responded.  I take it that their all new to Apple, and know
nothing of JumpStart.

     Anybody else got any ideas about the situation?
