The internal search function is temporarily non-functional. The current search engine is no longer viable and we are researching alternatives.
As a stop gap measure, we are using Google's custom search engine service.

A couple of points:
-Most likely your data files are all program described. This probably
means that not all fields are defined everywhere the same, especially as
to decimal places and the lengths of character fields. Many times, to
make a report fit on the paper, fields in the I-specs were just truncated.
-Most likely your OCL has a lot of file deleting and recreating, a real
pain for performance and it can be confusing to understand what is
happening.
-Chances are that there a lot of sorts in the OCL since the use of
logical files came very late in the Sys/36 life cycle.
-Because of the limitations of the hardware, many applications were
written as a whole series of small programs. The implications of
continuing this process can be unhappy users, and a modernized
application that is not at all modernized.
Here is the algorithm I use to do this sort of conversion: Find the
/smallest/ application and keep the spirit of the application, but
externally define the files and look at the heaviest used parts of the
application and totally rewrite those. Then, fill in the pieces from
exiting code. Do not use OCL, or even try to replicate the steps in the
OCL. Even if you get it right, its awful.
Repeat for each application, from smallest to most complex. (You learn
enough new each time so that when you get to the heavy stuff it goes a
whole lot easier.)
Good luck.

I was told it existed in school but was lead to believe it no longer

"modernize it". Is there a tool to help convert it to RPG or RPGLE code
similar to CVTRPGSRC?
