Description

This parameter limits the number of snaps which can be issued with any given snap title. That is, it prevents some bug from using up the snaps available as specified by the SNAPLIM parameter. The minimum value of SNAPLIMD is 0, which indicates that there is no limit (other than SNAPLIM, of course) to the number of snaps for any given snap title, and the maximum value is 32767. The default value is 3.

Usage notes

• The *SNAP snap title is not subject to SNAPLIMD, thus, whenever either the *SNAP or SIRIUS SNAPLMOD command is issued, each snap thus created is considered unique, and will not be suppressed due to SNAPLIMD.
• When the BUMPSNAP command is issued, each snap thus created is considered unique, and will not be suppressed due to SNAPLIMD.
• When the value of SNAPLIMD is greater than 0, the overall count of snaps (that is, the value of the SNAPID parameter) and the count for each snap title reflect snaps that were actually produced; snaps which are suppressed either due to SNAPLIM or SNAPLIMD do not increment those counts.

  One useful consequence of this is that, as long as SNAPLIMD had not been zero whenever any snaps occurred, you can be sure that SNAPID will always be less than or equal to the value of SNAPLIM, and so, to allow an additional snap after SNAPLIM has been reached, you can simply:

  RESET SNAPLIM 1+

• When the value of SNAPLIMD is 0, the value of the SNAPID parameter is incremented for each snap which is produced or which is suppressed, but the count for each each snap title reflects only snaps that were actually produced.
• If SNAPLIMD is (and has always been) greater than 0 (and so is used to limit duplicate snaps), to capture additional snaps for those which have already reached the value of SNAPLIMD, you can increase its value, for example:

  RESET SNAPLIMD 3+

  In order to capture these additional snaps, of course, you may also need to increase the value of the SNAPLIM parameter.

• The RESET examples above use the feature described in "Relative values for Model 204 numeric parameters".
• The table of snap titles used by the SNAPLIMD parameter can be viewed or re-initialized using the SNAPLIMD command.
