Suggested Resolution
If INCR is used, either allow any positive number (there may be some reason
to turn a table around several times) or allow any amount greater than zero
but less than a full turn (might use less than or equal to, instead).
If ABSL is used, the final position might be given in the range from zero to anything less than a full turn.
A better solution would be to use a wrapped linear axis for the rotary table. Then CCW, CW, and SHORT would not be used. A positive number would be a counterclockwise rotation and a negative number would be a clockwise rotation. Any n would be valid with either ABSL or INCR.

Warning!!
The following statement is only a resolution to a Standard Improvement Request (SIR) and is NOT part of the current DMIS standard, nor is it guaranteed to become part of the next revision of the DMIS standard even if voted and accepted by the DMIS National Standards Committee. This resolution is tentative because it may not be incorporated into the next version of the standard, it could be changed prior to the next release, or it could be changed as the result of the "public review and comment" period required for the next version of the standard. If you choose to use this tentative resolution, you do so at your own risk since at this time it is not part of the DMIS standard.
