return header # from GET_OFFSET_ARRAY?

[subtledoctor]

Maybe I'm dense... I've had some success using GET_OFFSET_ARRAY to retrieve information about spell and item headers, but it still seems a bit obtuse at times. So, at the moment I have something like this to detect all items with abilities that use the GAZE projectile:

OUTER_SET ind = 0
COPY_EXISTING_REGEXP GLOB ~^.+\.itm$~ ~override~
  PATCH_IF (%SOURCE_SIZE% > 0x71) BEGIN
    READ_SHORT 0x68 num_ab
    PATCH_IF (num_ab > 0) BEGIN
      GET_OFFSET_ARRAY ab_array ITM_V10_HEADERS
      PHP_EACH ab_array AS int => ab_off BEGIN
        READ_SHORT (ab_off + 0x2a) itm_proj
        PATCH_IF (itm_proj = 65) BEGIN
          SET ind = (ind + 1)
          [detect which header this is]
          SPRINT $gazeitems(~%ind%~ ~%SOURCE_RES%~)~%header_#%~
        END
      END
    END
  END
BUT_ONLY

Later I'm going to want to copy the items in that array and patch the particular headers in some way:

ACTION_PHP_EACH gazeitems AS ind => head BEGIN
  COPY_EXISTING ~%ind_1%.itm~ ~override~
    LPF ALTER_EFFECT INT_VAR header = %head% match_opcode = x timing = y duration = z END [etc.]
  IF_EXISTS BUT_ONLY
END

Question is, how do I record the particular header numbers in the array?

PHP_EACH ab_array AS ab_num => ab_off BEGIN
...

SPRINT $gazeitems(~%ind%~ ~%SOURCE_RES%~) ~%ab_num%~

or something
