DIR.LIT 3.3(160) enhancement: new /MEMREQ switch displays the memory required for static variable storage for programs such as LIT, RUN and SBX files in place of the file size. When both /SSIZE (sort on file size) and /MEMREQ are specified, it also sorts based on the memory requirement.
Note that the value displayed by /MEMREQ is only a total for the combined sizes of the fixed variables in the program. While this is far short of the total operating system memory used by the program , which includes dynamic variable, stack and other auxiliary memory allocations, it is a good measure of how large your job memory partition needs to be. This is particularly true since 6.3.1518 when the string stack was moved to dynamic memory. A reasonable rule of thumb would be to set your partition size to 300-500K larger than the largest /MEMREQ value for your application. Use DIR /MEMREQ/SSIZE to find the largest values; don't forget to also check the LIT files in SYS: since some of them may have large requirements.
