Re: System 3 Code

System 3 machines were mostly card machines.  They used 96  column punched 
cards to store data.  RPG responded to those needs, not to magnetic media. 
 You designed with record formats, matching records, level breaks, and 
left-side indicators.  there were no parms, no calls, no *INZSR, no 
externally described files, and no logical files.  you sorted the records 
to establish order for reports.   Source code was numbered in the first 5 
columns so you could put your card stack back in order when you dropped 
it.

Just a curiousity question ...

A contractor recently described some very old code as "System 3" code. Any 
idea
what this is?  RPG II is as far back as I go!  I do know it's running on 
an
AS400 in 36 mode.
