Thanks. Easy enough. An off-list communication described this:
MOUNT [devaddr],vol=(sl,volser)
Does "sl" stand for Standard Label" Is BLP likewise supported?
<SNIP>
Two different issues are raised by your questions. MOUNT defines the
type of labels that the volume has. The following are supported (as of
z/OS 1.7):
SL is standard label
AL is ASCII/ANSI label
NL is NON-Labeled
When you access the volume, you may then override the label information
(such as with BLP). However, if you change the first three records on
the tape (if you specified AL or SL) life may become interesting.
Also, if you are using AL and you make a mistake with your AL label from
within your program, the volume will be dismounted, (OPEN thinks it has
the authority to change the UCB bits and effectively cause an UNLOAD!).

Steve Thompson
