Since you plan on using them, I have included the source code below to save
you the trouble of re-creating them.

;
;********************
;
;   Macro SKIP_WLE
;
;   Skip the next instruction if W was less than or equal to the value
;   it was subtracted from.  This assumes that the carry flag has been
;   preserved from the last SUBWF or SUBLW instruction.
;
skip_wle macro
  if fam_17
         btfss   alusta, c
         exitm
    endif

         btfss   status, c   ;skip if no borrow occurred
         endm
;
;********************
;
;   Macro SKIP_WGT
;
;   Skip the next instruction if W was greater than the value
;   it was subtracted from.  This assumes that the carry flag has been
;   preserved from the last SUBWF or SUBLW instruction.

skip_wgt macro
  if fam_17

         endm
;
;********************
;
;   Macro SKIP_Z
;
;   Skip the next instruction if the zero flag is set.
;
skip_z   macro

    endif

         btfss   status, z
         endm
;
;********************
;
;   Macro SKIP_NZ
;
;   Skip the next instruction if the zero flag is not set.
;
skip_nz  macro

;   Macro SKIP_CARR
;
;   Skip the next instruction if a carry occurred.

;
;   Skip the next instruction if a borrow occurred.

;
;   Skip the next instruction if no borrow occurred.

;********************
;
;   Macro INTR_OFF
;
;   Globally disable interrupts without changing which interrupts are
;   individually disabled.  This macro together with INTR_ON can be used
;   around small sections of code that need to run with interrupts off.
