Before SQL got a full outer join I regularly used the cycle with M and L indicators.
I dont believe many people realised that the rpg cycle with M , L indicators was effectively full outer join, so easy to use with any nunber of files, and SQL still has no lookahead.

Jon,

I don't agree at all.
What's about with printer and display files?
It could be an advantage to know how indicators work.

Perhaps may a cycle program be faster than a SQL update, best with M and L indicators. Haha, it's a joke!
And sometimes, not all modern things are really economic.

Just my 2cts.
