Hello world, I'm writing a program in TurboPascal v5 and have, since I'm a novice at the PC's memory limitations, encountered a problem (at least I think it could be a problem :-)). How do I know how much of the computers memory a program is going to use (no dynamic allocation), and how does one go about to test this? I'd like the program to do something like "if mem_avail > size_of(this_program) then begin(program) else error(message)" I have some ideas of how to do, but I don't know how to create the environment to test them in :-) I've read the manual, yes, but I found no hints there unless I've missed the same page(s) every time. Also, I'm sorry if this isn't the appropriate newsgroup. thank you! - Tobbe --- tobbe@gamma.me.chalmers.se (Gothenburg, Sweden, soon winter, argh!)

Other than that, the program should automatically give you an error message if there isn't enough memory. If this isn't what you meant, I apologize. - Jonathan Watts jrwsnsr@jupiter.nmt.edu
