Re: ILE Concepts

I know what you mean Jon. Trying to get RPG programmers to break things
down into small pieces is like pulling teeth.

For me, a classic example.

Building a service program that returns multiple rows of data.

Build one big procedure that passes all the parameters and then return an
array of records. No, no, no

Trying to get people to understand you need to break down into small
pieces. One procedure to build data, one procedure that can ask how many
records and another procedure that receives one record.

One procedure that does one thing. Guess I had better get off my soap box.
