KBBVFND for Yottadb

A bare-bones string search in GTM globals or routines.

Trying to remember labels in routines is my short-coming.
While re-doing/updating this program, I added the ability to also
string search global nodes(subscripts) and their content.

The attached M routine (KBBVFND) is for YottaDB/GTM environs
only. I have no plans to make it available for any other environ
but it certainly can be modified by anyone who wishes.
