Very late to the game, but could you use one of the new vector string
instructions? Possibly a combination of VECTOR FIND ELEMENT EQUAL and
VECTOR STRING RANGE COMPARE. I've done nothing with this (yet), so I
can't provide any answers or advice.
You would have to be z13 or better to open.

1. Is there a machine instruction that will find one string within
another? That given "Now is the time" and "is" would find the "is" and
return a pointer to it? A machine instruction analog of Rexx POS?
2. Searching the PoOp for such an instruction led me to CUSE. It does
not seem that CUSE could be used for this - is that correct? If I am reading
CUSE correctly, then given "Now is the time", "All is well" and 2 or 3 would
return the position of "is". Is my reading correct? What would that be good
for? What would be a reasonable real-world use?
Thanks,
Charles
