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
