Hi Naomi,
This is what we use to limit the size to 512 MB

lcmemsize = SYS(1001)
IF(VAL(lcmemsize) > 512000000) THEN
  =SYS(3050,1,512000000)
ENDIF

>>= SYS(3050,1,val(SYS(1001))/8)
>>= SYS(3050,2,val(SYS(1001))/8)

>>Should limit your 1 GB machine to about 256 K, evenly split between the Foreground and Background buffers.
