Program Only Uses Memory Below the Line

If your program only needs to address memory below the line, you should:

  1. Set Max. memory below 16Mb line to the maximum amount of memory below the line that your program requires. The default is 3Mb and the maximum is 16Mb.
  2. Set Addressing mode to AMODE(24) for the main program and for each program that the main program loads.
  3. Omit the LOC parameter from all GETMAIN or STORAGE OBTAIN macros issued by your program.
