Re: Moving to RPG 4

Jim,

Nice overview, One thing that I would like to add, is that since RPG off all 
flavors have a bias
towards fixed column formatting of the language, there was a radical change in 
the shift from RPG3 to
RPGIV.

One can take an RPG36 source member and change it to RPG with possibly a 
minimal amount of compile
failures, but to change a RPGLE source member to RPG guarantees compile 
failures.  The specs have a
new, expanded, format.
