Try putting a line like numeric digits 20 somewhere before your first use of the storage function.
Some of the storage function calculations need more than the default 9 digits' precision, depending on address values and memory contents. I've had inconsistent results when I've forgotten to set numeric digits to a decent value. That's why Mark Zelden has the comment /* dflt of 9 not enough */ in his IPLINFO exec. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
