QuickBasic program memory leak.

Guest · May 29, 2017

The OS I'm making in quickbasic accesses a different file with the SHELL command when you press a specific key. After a while of doing this, it runs out of memory and the PC crashes.
Is there any command that'll let me exit to a file?

I think you would get more help in the open source software section of the forum.

What do you mean by exit to a file? Saving something to a file and stopping the program?

Are you talking about Microsoft' QuickBasic for DOS??

Yes I am using QuickBasic 4.5 for DOS.

You might not know that, but DOS memory space is limited to 640kb (kilo-bytes, as 640x1024). If your program is not careful about releasing memory, that's expected.

Why are you using (or learning) something which was "modern" 30 years ago?

The clear command closes all files and erases all varibles. You may want to keep the varibles by using the close command instead. Close just closes a file you opened to write, append, or read from.
