I thought that the Cycle is what makes RPG [different from; better than;
faster to code than] most other programming languages.
The cycle is what made RPG the best language for its original purpose:
printing reports. The cycle allowed you to easily and quickly define a set
of operations to be performed on a record, and then quickly repeat those
operations over millions of records in a file, either generating another
file or a report. This together with its tight integration to the database
made the early of RPG unbeatable for data processing applications.
Today, though, the cycle is more of a niche function. RPG's tight
integration to the database is still a powerful feature, one not matched by
any other language. But new features such as its integration to other
languages through ILE and its ability to use highly structured programming
techniques to define powerful business rules has moved it from just a data
processing language to the premiere language for defining business rules.
Of course, I might be biased <grin>.
