I recall reading tapes (on MVS) produced on VAXes or some other 'foreign' computer system. They had 17 character ANSI file datasetname values (17 chars being all the HDR1 label has space for). Spaces and other special characters are valid in such names. The JCL ref manual has an example of a valid DSN='AB CD'. I don't know whether it'd be valid to define a datasetname on such a tape as having just a single-letter name. I don't see why not though. -- Jeremy Nicoll - my opinions are my own. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
