Hi listers! Do you have any idea on how to get only the last record of a very big file using either REXX or some other method? I will want to prevent reading all file records in any any case. <snip> I would allocate the file with DISP=MOD and write one record and then do a NOTE. Then I would close the file, and reopen INPUT. Then I would issue POINT and do a read backward. Fastest way I know of to get there w/o having to read the whole file, or do a catalog lookup, get the last volume (or only), read the VTOC, get the EOD info...
