Debug Program - RPG3 and older only

Back in the dim distant murky past of collumn based RPG we used to debug using volumes of printed source code on strange, hugely green lined, printouts.

The debug program utility changed all that. It shows the source code and steps through lines by line for each line of code that is active. It basically does everything that the new ILE Debugger does. But for smelly old RPG2 and RPG3.

I will add some screen shots... but to be frank... I havent used this command since 1998.

And my oldest dog isnt as old as this command. And my dog is grey, half blind and incontinent.
