Hi
Why do work the 1st and 2nd lines below but not the 3rd? Note that the LN EQU works fine and its value is 4. 0001AE D503 B408 A7A9 01408 007A9 691 CLC =AL4(TKJSPFX),TKDSNM 00004 692 LN EQU L'TKJSONPF 0001B4 0000 0000 0000 00000 00000 693 CLC =AL(LN)(TKJSPFX),TKDSNM ** ASMA151E Literal expression modifiers must be absolute and predefined - =AL(LN)(TKJSPFX),TKDSNM TIA João
