Yes, the size of the dataset, not the size of its records, tracks, or creator.
The environment is not TSO, so LISTDSI is out. Assembler or Rexx, makes no never mind to me. I can pretty much translate betwixt the two. The perfect piece of information would be the total number of used tracks. Yes, I can do that with CAMLST LOCATE and OBTAIN. The situation involves very large datasets, so multi-volume is a reality. Perfectly do-able with CAMLST LOCATE and OBTAIN, but a lot of work for a simple answer. I could settle for primary and secondary allocation units and quantity, but primary quantity appears to be elusive (see earlier notes). Do you have a source for primary quantity for existing datasets? It's around somewhere because ISPF 3.2 displays it. Where? Secondary quantity is in the DSCB-1 but not the primary (or am I missing it?). You could think of the problem at hand as being "if I were to copy this dataset, how large a dataset should I allocate to hold the copy?" So the actual number of used tracks would be a perfect answer, but the original primary and secondary allocation would be a good estimate - or rather, a set of values that worked once for this amount of data and might very well work again. I'm in somewhat of an R&D mode on this problem so I don't have exact specifications for the problem. Thanks for your help.

Based on your other comments, it appears you want the allocated or used size, and not record size, block size, track size, primary allocation size, or secondary allocation size. Do you want this in bytes, tracks, cylinders, or something else? Do you need to do this programmatically, or could you use the Data Set List Utility of ISPF? If programmatically, does it have to be assembler, or would REXX suffice? Does the LISTDSI REXX function have the info you need? ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [EMAIL PROTECTED] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
