I copied the code starting:

*--------------------------------------------
* EnumPrinterFormClass.prg
DEFINE CLASS EnumForms AS Custom
HIDDEN hHeap, nInch2mm, nCm2mm, nCoefficient

to EnumPrinterFormClass.prg and placed it in the Code in the project, when I built it, I got some error:

Compiling c:\myproj\enumprinterformclass.prg

Error in line 228: Nesting error.

Error in line 485: Nesting error.
ENDDEFINE
Error in line 487: Statement is only valid within a class definition.

am I missing something?

thanks for the help.
