It's easy to suspect that there's a common subroutine to add record to target file, called for all transfer modes, that converts empty records to spaces. And that behavior may have been inherited from VM/CMS where empty records are strictly prohibited by the file system.
And they might consider it an incompatible behavior. It might break end user code that does LH; BCTR; EX; MVC to copy variable length records. Same reason that ISPF/PDF changes empty records even with SET PRESERVE ON. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
