There should also be mention of the allowable range of values: 0<n<=32760? 0<n<=BLKSIZE? 0<n<track-size? 0<n<=65535? (The last is the maximum supported by channel programs, or was.) Are unsigned halfwords supported? This became an issue about the advent of the 3380. Clearly the present text of the manual engenders confusion and dissent. -- gil ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
