VMS Exceptions

The TMSVMVLT program reports on exceptions encountered during processing. Patterns that had no movement and duplicate slot numbers are examples of exceptions that would be noted on output of this program.

Avoid using the following keyword combinations when defining your patterns:

JOB= and SEPJOB should not be used on the same DSN= statement. JOB= will be honored.
CR= and E= cannot be used on the same V= statement.
VR= and E= cannot be used on the same V= statement.
LU= and E= cannot be used on the same V= statement.
If V=vltx is specified more than once in a pattern, the locations should be contiguous.

Example:

Invalid	Valid	Valid
DSN=ddd	DSN=ddd	DSN=ddd
V=VLT1,VR=5	V=VLT1,VR=5	V=LIB,CR=2
V=VLT2,C=1	V=VLT2,C=1	V=VLT1,C=5
V=VLT1,EXP	V=VLT3,EXP	V=VLT1,VR=1

The example on the left is invalid because VLT1 is specified as both the first and last location on a pattern. This has been corrected in the example in the middle. The example on the right illustrates multiple specifications for VLT1.
