Labwindows for DOS (2.31) running under Windows98

[Paul Rocca]

Should LW/DOS work reliably under windows 98? I cannot get the uiedit program to work without rebooting to DOS, though the uicode and other programs seem to work.

No, LabWindows/DOS is a 16-bit DOS program and will likely have issues working under the 32-bit DOS shell. You would need to reboot into actual DOS.

hmm, as I thought. My problem is that I have been dumped with a large quantity of LW/DOS source code, compiled with VC 1.52.
Due to the size of the exe, I can only get the Codeview debugger to open it running under windows98 where it can have lots of base (<640k) memory, but as soon as I get to a loadpanel call it crashes with -12(out of (extended?) memory) error.

Any advice? Do any of the 3rd party memory extenders work with LWDOS?

I remember that Borland use to have a serial debugging tool, but VC/Codeview doesn't seem to have this option.

Any other suggestions or advice gladly accepted

3rd party memory managers should still work will Win98 in DOS mode. I used to use QEMM. Something like that would probably be able to setup the extended memory the way you need it for that program. It's possible you could do it with himem.sys as well which is the basic DOS memory manager that comes with Windows. Good luck.
