SHOW many be a misnomer. It's a way to do a pick-list using the dictionary & LIST-like syntax.
It came from PI. They probably should have called it PICK, but that would be anathama. They did not even admit that that particular word was in Webster's Dictionary.
Example (I hope google displays this with fixed width font):
>SSELECT VOC WITH @ID LIKE "&..." BY F2
14 record(s) selected to SELECT list #0.
>>SHOW VOC TYPE F2 F3 HEADING "'TL'Pick some stuff:"
05:07:12pm 07 Aug 2015
Pick some stuff:
VOC.................. TYPE F2........... F3...........

^^ - Refresh ? - Help on SHOW [Page=1] [Selected=5]
(Last) -->
Above, I answered the prompt with "1 3-5 13"
SHOW put asterisks by those line numbers.
I can page forward and back if multiple pages, and add or clear items selected.
When I finally "Q" out, I'm left with an active select list.
In this case, the select list would have 5 items: &ED&, &TEMP&, &XML&, &UFD&, &PH&.
When greenscreen was king, this was a really nifty tool.
Now, it's still handy for developers & troubleshooters working at TCL.
But SHOW can't handle Pick-style dictionary items. (TYPE, F2 & F3 are I- or D-types.)
That was my question: if anyone had adapted it for A-, S-items & correlatives.
