CGIDEV2 (and the COBOL version) are very similar to the eRPG SDK with the
template method.  I just chose to do things a little different that I felt
were more intuitive, less memory hungry and faster executing.

But, if COBOL is your choice then the COBOL version of CGIDEV2 may be a
good choice.

Also, feel free to contact me offline if you want.  If I had to put
together "COBOL Friendly" interfaces for the eRPG SDK it wouldn't take much
time.
