'Prototype PostIt! script creator. Created April, 1993
'This  simple  program  creates  a  newer  type  of  PostIt!  self
'extracting script that decodes very quickly and can handle  files
'up  to 34,000 bytes.
'
'This script eliminates the "middle  man"  by  outputting  to  the
'destination  file directly in the G sub.  This speeds up decoding
'and lowers memory usage  because  we  don't  have to first append
'each G line onto a string before  the  file  is  decoded.   Since
'we're  not using strings anymore, the only limit that remains now
'is QB's  internal limit on  how  large  a program may be(it might
'actually be a dgroup limitation, not positive yet).
'
'I haven't extensively tested the scripts this program creates, so
'use with caution.
'
'To decode a script created by  this  program  directly  from  the
'command line just type:
'
'       QB/run<script> or QBASIC /run<script>
'
'Where  <script>  is  the name of the script to decode, of course.
'You still have to edit  out  any  garbage  in the file, I haven't
'worked out any way for the self extractor to do that, yet...
'
'If the file gets decoded correctly, the script will  exit  right
'back   to   DOS   without   making  you  lift  a  single  finger.
'(Unfortunatly PDS prompts  you  if  to  save  the  file after the
'script is decoded.  I don't know if there is  a  way  to  disable
'this, so use QB4.5 or QBASIC instead.)
'
'If a  CRC  error  does  occur  the  script  stays  in  the QB/QBX
'environment so you can check it out for garbage.
'
'If  you  don't  want  to  exit  back  to DOS after the script is
'decoded, then just don't use the /run option on the command line.
