>In the Main.prg of the project I'm working on, I get the error "variable 'varname' not found" on the line APP_GLOBAL = NEWOBJECT(APP_CLASSNAME, APP_CLASSLIB). I looked in my project classes and sure enough, APP_CLASSLIB does not exist.

Those 3 APP_WHATEVER's look like they're supposed to be constants, which are defined elsewhere with #DEFINE statements -- either at the top of the main.prg or in a separate file with ".h" extension which is referenced with a #INCLUDE directive.

So, either the #INCLUDE statement is missing or the .h file is missing.

For example, you might have a file called rodsapp.h that contains the following:

#DEFINE APP_GLOBAL oApp
#DEFINE APP_CLASSNAME myapp
#DEFINE APP_CLASSLIB appclass.vcx

Your main.prg might then have a line near the top:

#INCLUDE RODSAPP.H

At any point after that command, you can refer to APP_CLASSNAME and it will be translated to mean "myapp". This is done so that you can just change the settings in the .H file, recompile, and redefine the object reference name of the app class, its class, and class library without changing your program. This is often done to allow flexibility in frameworks.
