Compiling in Windows XP

This article only applies to the DOS/QuickBasic 16-bit version. It is not relevant for the current 32/64 bit Windows/Linux/Mac/etc versions

If you are using Windows XP, NT or 2000 to compile the old DOS version, you need to pre-set some environment variables before you compile.

Right-click on "My Computer" and pick "Properties"
Go to the "Advanced" tab.
Click the button labeled "Environment Variables"
You need to create 5 variables, which are the same ones found in the env_set.bat batch file.

QBVER = 4.5
QBDIR = C:\QB45
OHRRPGCE = C:\OHRRPGCE
QBEDIT = QB.EXE
LINKEXT = l

Alternatively, you can add the line

 call env-set.bat

to the top of your compile.bat file, assuming you have edited env-set.bat as necessary.

Then you can open a DOS prompt (START->Run and type "CMD"), and change to the OHRRPGCE directory with the command:

 cd c:\ohrrpgce

And you can compile with the command:

 compile
