You could start with RTFM... pages 2-64R et al. It's easiest if you know the datatypes, then just use the appropriate popping functions, e.g. popdub(&v3); popquote(v2,len); popshort(&v1); >Because, often arguments order and arguments type change. Sometimes it can be short, char, double or any combination of them. How to know the types of them? > Thanks. If you don't know the data types, you can peek into the value structure and check the v_type field, and handle accordingly. -- Alan Denney aland@informix.com {pyramid|uunet}!infmx!aland "Eventually people realized that the Information Superhighway was essentially CB radio, but with more typing." -- Dave Barry
