  Hello regular posters and occasional lurkers of this group, 
  
  For those more than vaguely interested in GFA 3.XX, better yet:
  heavily involved in it, 
  hear me cry:
 
  I simply wish to execute any specified program, 
  chosen via a fileselector box from my application, 
  whilst keeping my application resident.
  
  There. Pretty simple really. My Data-Becker manual tells me to use: 
 
  RESERVE <some amount of memory>
  EXEC 0,"SOME.PRG","",""
  RESERVE 
 
  in which the last RESERVE should reset things as they were.
  
  Since the RESERVE command as such is sort of obscure to me
  (HOW would *I* know what's needed for the application of John Doe's choice)
  I simply type RESERVE 1. 
  Yes.
  One byte. Just to make EXEC happy, which won't work when I'd leave out
  a RESERVE command before it.
  Does it work?
  Well: for most applications it does. Yet not for all, which irritates me.
  Sometimes, upon returning to my resident application, 
  the last RESERVE yields a "* error in RESERVE" message.
  
  QUESTIONS:
  * Did anyone ever play with those commands before?
  * How would I go about using the RESERVE command sensibly, 
    not knowing what to reserve for an unknown program?
  
  Anyone who can stop GFA 3.07 from telling the world what a lousy programmer
  I am; please respond to:

  or just to this newsgroup.
 
  Thanks in advance!
  
  With kind regards,
