Thanks Tony! My intent is to merely interrogate to ensure someone hadn't left an undesired value after a change window. Traveling down the path of CVT > TCAST > TCASUMAX using Rexx storage calls (via NetView) yields a null value. The old doc mentioned TCAST was located in "System common area", but perhaps it moved to private? Anyway, I appreciate the help!
