Rick, Here's how I handle it assuming all references fit into a single source file. The code fragment: lsl.w #1,d0 ;multiply index by 2 for table offset lea cmdtable(pc),a0 ;get address of table move.w 0(a0,d0.w),d0 ;get routine offset adda.w d0,a0 ;calculate routine address jsr (a0) ;jsr to routine The table: cmdtable: dc.w (FUNC1 – cmdtable) dc.w (FUNC2 – cmdtable) … The advantage of this is that there is no relocation data needed in the load file, which makes the code directly ROMable and self-relocating. If you for some reason need a long offset, the assembler will let you know by telling you the value is too large to fit into the defined word. You can then fix it by simply doing a S/R for a 'dc.w' and replace with a 'dc.l', and finally changing the 'lsl.w #1,d0' to a 'lsl.w #2,d0'. -Dean
