RTFM? From the z/OS V2.2 TSO/ REXX Reference, EXECIO, DISKW parameter: Note: 1. The length of an updated line is set to the length of the line it replaces. When an updated line is longer than the line it replaces, information that extends beyond the replaced line is truncated. When information is shorter than the replaced line, the line is padded with blanks to attain the original line length. -- Peter Hunkeler ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
