or RPG/400 source members to the RPG IV source format at compile time.
The Conversion Aid does not support converting RPG II source programs
to the RPG IV source format. However, you can use the RPG II to RPG III Conversion Aid first and then the RPG III to RPG IV Conversion
Aid.
The Conversion Aid does not re-engineer source code, except where required
(for example, the number of conditioning indicators.)
The Conversion Aid does not create files. The log file and the output
file must exist prior to running it.
