QSAM to a traditional PS file with the process you described is certainly going to write only short blocks. Given the amount of data involved, would it matter?
However, besides USS files, you could consider an ESDS. VSAM maintains its CISIZE and blocksize quite rigorously. And it should be very safe. sas ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
