How can I build a project made for DOS?

Question

 Hello!
 I've a project I'm afraid was made 15 years ago by somebody with a DOS version of LabWindows. I'm trying to compile it with LabWindows 7.1.1 and I've some "link error" and "syntax error" (about 80). I've tried with the "translate" tool but it doesn't change. How can I manage?

I'm very much afraid you are in the wrong forum here!!
We talk here about LabVIEW which fortunately never had to run under DOS
;-). As to your question itself it could be tricky. If the code has
been written in the C slang of LabWindows for DOS you should be able to
fairly easily get it up to compile in a recent LabWindows CVI version,
although there have been some issues about converting from DOS to CVI
due to 16bit -> 32bit issues and I'm not sure there is still good
documentation about that. The move from DOS to CVI was after all more
than 10 years ago.
If the program is written in the QuickBasic slang LabWindows for DOS
also supported, you will first have to find an old LabWindows for DOS
installation to let it translate the QuickBasic code to C before you
can attempt to import it into LabWindows CVI.
Just looking at the code and trying to recode everything in LabWindows
CVI or maybe LabVIEW ;-) may be not such a bad idea after all. It could
make sure that the application is coded in a good way as ol' LabWindows
for DOS had quite some limitations due to its dual language
QuickBasic/C support.
