Using the Dash

You can use the dash (‑) masking character to specify an extended resource key mask as follows:

• When the dash (‑) mask character is at the end of a qualifier in the extended key, it matches any number of characters that complete the corresponding qualifier in the resource name.

  Extended resource key     Portion of Resource Name
  TEST.NAME‑     matches    TEST.NAME
                            TEST.NAME123
                  but not   TEST.NAM        (too short)
                            TEST.NAMX       (different character)
                            TEST.NAME.2     (extra qualifier)
  

• When the dash (‑) mask character forms a separate qualifier in the extended key, it matches zero or more qualifiers in the resource name until the next qualifier of the extended key (if any) matches a qualifier in the resource name.

  Extended resource key    Portion of Resource Name
  TEST.‑        matches    TEST
                           TEST.ABC
                           TEST.ABC.DEF
  
  TEST.‑.LAST   matches    TEST.LAST
                           TEST.A.LAST
                           TEST.ABC.LAST
                           TEST.A.B.LAST
                 but not   TEST.A          (missing last qualifier)
                           TEST.LAST.LAST  (matches first two qualifiers)
  

• When the dash (‑) character occurs at the beginning of or between the characters of a qualifier in the extended key, it is treated as a literal character.
