Re: Any way in the CL program to find the length of the character datastored in a variable? -- MIDRANGE-L

This is interesting - which really is the bigger hit on performance. I think it depends. Using %SST in a loop could very likely take more time than a single call to a program that uses a more efficient loop - probably in some way that uses pointers and doesn't need to resolve the %SST for each test character. I can see that a 256-character variable that has only the 1st 3 characters filled would take longer with %SST than with a call to QCLSCAN. But it probably does not matter too much, unless this is repeated over several hundreds of thousands of records or values, say.

Still, it would be an interesting test. Maybe I'll try it when I have some time.

But I would use a substring method myself - no reason to call another
program and take the performance hit when you can do it in a loop with %SST.
