Re: Converting RPG to RPGLE

[Jerry Adams <jerry@xxxxxxxxxxxxxxx>]

Sometimes the conversion and subsequent testing can be very helpful.


Part of a project on which I am working contained an RPG36 program.  
Since I had a few minutes to burn, I converted it to RPG IV (free 
format); aka "the whole nine yards."  Since I don't like the /end-free, 
/free bracketing around MOVE's and ADD's, I converted them to EVAL's.  
Testing blew up because, as we all know, EVAL's won't roll over the way 
ADD's and such do.  Seems this simple little report had in one section, 
anyway, when wrong for years.
