It's not even close to implausibly huge. I got so tired of it, I wrote some stem-based buffered I/O routines (using both Value() and Interpret, naturally; sorry, Gil).

[External Email. Exercise caution when clicking links or opening attachments.] Right, it appears to be magic -- "just say EXECIO and presto there's the record count in STEM.0" -- but under the covers it is reading through the whole dataset and counting. Rexx is all 31-bit, right? So the limit would presumably be something in the 1 to 2 GB range. That is not an implausibly huge dataset. 1GB is what? 800 cylinders or somewhat more, depending on blocking, short tracks, etc.?

It's sort of hidden and would need a large memory allocation for the stem. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN Confidentiality notice: This e-mail message, including any attachments, may contain legally privileged and/or confidential information.
