RPG Three becomes Four - Step 2 of 4
CVTRPGSRC - IBM Command to upgrade RPG3 to RPG4
After running CVTRPGSRC on the old source a new member is created in QRPGLESRC:

As you can see the code if more or less the same, with the exception of few elements to make it more readable.
It's still using indicators, but if/do loops are now completed with relevant ENDIF/DO and EVAL statement have apeared.
Note - make sure any /COPY entries are also upgraded - otherwise trying to suck in RPG3 code from copybooks will upset the compiler
So far it's all been automatic, the CVTRPGSRC command is a wonderful thing.
Next step is to tidy up the code further so it morphs from a hybrid RPG3-4 to full blooded RPG4
