Commas are *very* important in AR-mode You have coded "LAE R3,0(R4)" - which is the same as "LAE R3,(R4,R0)"
Coded that way there is no automatic way that AR3 is going to inherit the AR4 value. You need : "LAE R3,0(,R4)" This will ensure that AR3 is populated from the AR for the referenced base register R4.

What would the sac value e.g. 256,512,768 have to be that when using the LAE instructions with the following operands LAE 3,0(R4) would AR3 get loaded with AR4 . Second what value does the displacement play in the instruction Thanks ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@bama.ua.edu with the message: INFO IBM-MAIN
