Beste Stijn,
The helpfile of -postgr3- contains examples you can directly
copy and paste in your do-file editor and run. Can you get
those examples to run? If you can't there is something wrong
with your installation, most likely -spost- isn't installed.
To find that out, you can type -which prgen-, I get:
c:\ado\plus\p\prgen.ado
*! version 2.0.4 23Jun2005 : _pexstring bug fix (2)
Otherwise you will get:
command prgen not found as either built-in or ado-file
Hope this helps,
Maarten
