Re: RPG II to RPG ILE

[Pat Barber <mboceanside@xxxxxxxxxxxxxxxx>]

A "little simpler" way to handled workstation programs in RPGII is
to fire up S36ee and compile the source as per normal. One of the
side benefits of doing that, is the compiler will also create a
new source member using the program name and place the resulting
DDS source in a file called Qs36ddssrc. You then have the regular
old DDS you are familar with and proceed with the conversion.

Some of the conversion aids work well, but the resulting source code
looks pretty bad with miserable field naming like FLD01,FLD02,etc,etc.

Using the DDS and some minor changes(most of the time), you can convert
a typical RPGII to RPGIII with little trouble. Yes, you can then
run the CVTRPGPRG and produce some ILE "like" code.
