But there are significant missing pieces that make life quite difficult for many cases. Notably, the input and output types of external functions are constrained to be the same, so that one cannot write an external function that takes, say, character (SETC-type) input and returns numeric (SETA-type) output. I know this, and a number of others are on your List, and presumably awaiting business case justification. Tony H.
