Cause: All available extents have been opened and the program requires additional extents.
System Action: If SYSLOG is assigned to a keyboard, the system waits for an operator
response: otherwise, the job is canceled.
Programmer Action: Check all extent cards for the file in error for sufficient size allocation. If
the extent information was submitted using standard (permanent) labels, use the LSERV output
to check the extents obtained. Resubmit the extent information with sufficient disk space
For a diskette file, open determines the beginning extent limit on each volume by giving the
user the next track after the last active track on the volume. The end extent limit is the last
record on track 73. This means that from 1 to 73 tracks could be allocated by open for each
diskette. The user should determine the space available for use on each diskette, and add
more volumes if the above mentioned allocation scheme would require them to write the entire

1. Type CANCEL or CANCELV or press END/ENTER to cancel the job, or
Type DSPLYV to obtain a VTOC dump, then type in new extent limits in the format:
relative track [,number—of-tracks]
where relative track equals the track address relative to zero, and number-of-tracks equals
the number of tracks required. If number-of-tracks is omitted, two tracks are assumed.
OPEN creates an extent with the specified number of tracks, using this relative address
and the information from the last extent opened.
2. If standard (permanent) labels were used, execute LSERV and return the output to your

2) Type in '354OGO' (OPEN will determine the new limits on the additional volume).
