DOS开发编程 & 发展交流（开发室） » Regarding the problem that the program cannot run after being larger than 64K

My program, after compilation and linking, is about 60-70K, in small memory model... I found that on some DOS machines, it can't run when exceeding 64K, but on some machines, it can run... The program hasn't changed... Why is this?

All added, is there any limitation under certain circumstances?

Believe it is a problem with HIMEM and EMM386 configuration. Here are some files and documents that can replace HIMEM and EMM386. There are examples inside. Although it is in English, you can give it a try: http://johnson.tmfc.net/dos/driver.html

Compile to Large mode 44 ---------------------------------- After compiling to L mode, the program has become much larger!

1、Can the owner explain what program you are and what compiler you use? 2、Small memory model, due to the "segment" reason, because the limit is 2^16 = 64k, so...

The person upstairs, my compiled executable file exceeds 64K.
