Sorts have "compiled" their key compares into executable code for as long as I 
can recall.

Rules, rules, rules!  But I would hardly be surprised if the DFSORT control 
cards were shown to be Turing-complete in which case they must be considered a 
pogramming language.

(Don't tell your customer, who seems determined to use JCL as if it were a 
programming language.)

A very simple Rexx EXEC might use a compound symbol as a table.
For large data sets this is inappropriate and JOINKEYS/COUNT is more suitable.
