You must periodically copy A$ to another variable and
clear it.  Or , before the length of A$ gets out of hand
process the data that you already have in it
and clear it.  Else you will hit the string length limit.
Note that with that much data to handle, you can't just
load it into variables or arrays unless you use XMS or
EMS to hold it.
 
ie:
 
  DO UNTIL EOF(ReallyBigFile)
     Read 10 records (or 100 or whatever)
     Do something with those 10
     A$ = ""
  LOOP
 
or some such.
