EQU is purely a text substitution. So everywhere you have abb1 it is the same a putting $.

The iprv block is assembling "mov edx,$".

Its sad.

My variant

Code:

macro list_txt a,[b] { local .l1
      common
      forward
      .l1:
      a equ .l1
      db b,0
      }
;in data section
Dat_A: list_txt abb1,'55','777','8822'
;in code 
irpv v,abb1 { mov edx,Dat_A#v }
