Chuck,

 True, when connected to a DB2 host, it did support RLA.  I had a 
"perfect" project to use VARPG, but it required keyed random file 
access and printer file output, as a standalone PC application.  It 
would have been deployed to numerous clients.

 Another possible issue: All the code, besides the DDM aspect, ran 
on the PC.  That is not the same as a fully integrated GUI being 
driven by a host application.
