In my tests, CHECKR performed at least 30% better than %len(%trimr(s))

Definitely something to keep in mind, for cases where I can't simply calculate the value, based on the lengths of what went into the field.

At any rate, calculating the value, rather than calling %LEN(%TRIMR()) cut processing time per record by about 31 milliseconds out of a total of about 55 milliseconds. Or in more concrete terms, the time to process and deliver 5012 records dropped from over 4 1/2 minutes to about 2, running on a 170.

Thanks to all who had anything to say.
