Sb: #Environment Size Fm: Charles Robertson 70130,330 To: Kerry Wilson 71006,440 (X) kerry, that is true...although when you EXIT back to the program all that space is returned to the operating pool.....HOWEVER...this is NOT true of resident programs. i patched my 3.20.22 to have 2K of environment space long ago because i use many "SET=" statements in my autoexec.bat file. i found out that since all TSR's also inherit a copy of the environment set when they are run...so if you have a 400 byte TSR and an 1500 bytes of environment used the resident program will take up 1900 bytes! not 400!...i freed up over 14K of DOS memory by moving the SET= commands after all my little TSR's and even did a "SET COMSPEC=" at the start to free up those few bytes... hmmm...i think i promised david a transcript of that patch...maybe i better post it now? ----------------------------- Fm: Dan Robins 70007,3264 To: Charles Robertson 70130,330 (X) Charles, RE: The "SET=" commands after loading in TSR's..... Thanks for that tip Charles! Never would have thought of that (and maybe the reason some of my memory has been going faster than expected). That's what's nice about this forum, folks like you passing on some handy information. Dan
