Note that RPG IV can do just about anything that could be done by earlier versions of RPG such as RPG/400 and an enormous volume of additional capabilities.

Fully free-form RPG
RPG now allows for a syntax which contains no columns at all; it is fully free-form, beginning in column 1. To use, the first line of code must be **free starting in column 1. There is no predefined final column. There is one limitation: the program does not allow ANY columnar (fixed form) RPG, including comments with an asterisk in column 7. RDi 9.5 recognises this new syntax. It is provided as a PTF, but is not in a group or TR - it must be ordered separately. First available in November 2015.
7.1:
- SI58136 (compiler, target-release *CURRENT only)
- DB2 group PTF SF99701 level 38 (SQL precompiler)
7.2:
- SI58137 (compiler, target-release *CURRENT)
- SI58110 (compiler, target-release *PRV)
- DB2 group PTF SF99702 level 9 (SQL precompiler)
