To "squash" a dataset into a dataset with LRECL=80, RECFM=FB, BLKSIZE=2120 use the TSO TRANSMIT (a.k.a. XMIT) command with the OUTDSN keyword.
Instead of actually transmitting the file somewhere else, it will put the output into the dataset named in the OUTDSN keyword with those attributes. To restore the file to it's original format, use the RECEIVE command with INDSN. You name the "squashed" dataset in the INDSN and receive it from there as you would a normal RECEIVE. The DCB attributes will be taken from the INDSN, but you may need to specify SPACE for the received dataset if the defaults aren't enough. --Roger ---------------------------------------------------------------------- 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
