Unresolved procedure call

Post by Calcman54 »

In the Financial Decisions Pac module there is a procedure called *DATA. In that procedure on line 21 the instruction is XROM 29,08. Does this mean that I have to have another module loaded to resolve this call? There is another instance of it on line 8 in procedure *OUT.

XROM 29,08 is "PRA" from the HP-IL printer module. I think that you'll get the desired result by adding the printer module that ships with the DM41X.

XROM 29,08 is the PRA function on the original 82143A dedicated HP-41 printer and also PRA on the HP-IL printer...just for completeness here.

When the Financial Decisions rom was created, it would have been the 82143A dedicated printer of course. Thanks to the good decision making of the HP-41 team, the HP-IL printer used the same XROM commands to ensure it worked well.

And of course :-) the HP-IL printer rom is the one supplied for the DM-41X which still executes this program correctly.

What a tremendous achievement.

Actually, the DM41X printer implementation is based on the 82143A ROM and not from the one coming from the 82160A.
