Here is a very simple source file that illustrates this: 1 TR ON 2 ORG $4000 3 4 LDA #LONG 5 6 FNDVAR2 NOP 7 DS \ 8 LONG EQU *-FNDVAR2 9 END Illegal forward ref in line: 8. But the LONG is still correctly computed (accoring to listing) as value $FE. However, whenever I change line 2 so that the distance between *(from line 8) and FNDVAR2 becomes greater than 256 bytes (i.e. 2 ORG $3FFE), the error is not raised anymore. My current thinking (but w/o any concrete fact) is that it might be connected to how the page zero adressing is handled within Merlin 8. I noted the same behavior in v2.48 (DOS3.3) and v2.58 (ProDOS) of Merlin 8. Any feedback would be welcome in this thread.. Thank you for reading, Benoît -- Growing old is mandatory.. growing up is optional.. But the other way round is as true.
