Post by thread:[PIC]: MPASM Macro help Please

Greetings all, I posted this question last night, but it never showed up on either of my accounts. Please excuse me if you get it twice. I'm just learning to write macros, and I have an ambitious one that is working, but not quite the way I'd like. If I invoke the macro only once, all is well. But if I use it twice (or more), I get the following error: : Address label duplicated or different in second pass I understand the cause, but I'm wondering if there's a way I can include branches to labels within a macro without resorting to counting instructions and using BRA $+xx. (which works for now, but makes editing a pain) I'd be grateful for any suggestions. Thanks, Lyle Hazelwood -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you. See http://www.piclist.com/#topics

Hi You can "include" labels in a Macro by making them LOCAL to that macro. ex: test MACRO LOCAL loop ;, labeln..... loop GOTO loop endm -- Quentin spam_OUTqscTakeThisOuTiptech.co.za http://www.iptech.co.za -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

> Address label duplicated or different in second pass Use the LOCAL directive to declare labels that will be unique to each macro invocation. See STD.INS.ASPIC at http://www.embedinc.com/pic for lots of macro examples. ***************************************************************** Embed Inc, embedded system specialists in Littleton Massachusetts (978) 742-9014, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

Thanks Quentin, works like a charm. I had seen the LOCAL option for variables local to a macro, I didn't realize that it could be applied to labels as well. Lyle {Original Message removed}

Greetings all, I'm trying to get a grip on macros, with an (overly) ambitious first project. macro is working well if only invoked from one place in the source. If I invoke it from two places, the labels used inside the macro generate an error, : Address label duplicated or different in second pass I understand the cause, but is there some way other than doing braches by literal value instead of labels? I'd rather not count instructions for each conditional branch. Any suggestions are appreciated. Lyle Hazelwood -- http://www.piclist.com#nomail Going offline?

Use the LOCAL directive.

Olin, Thanks for the help (again). The message you replied to was posted by me on Sunday evening. By Monday morning, I had not yet seen the message from either of my PICLIST accounts, so I reposted it from work, with a comment at the beginning that the original post never made it through. I noticed this morning, as you did, that the original "lost" message finally made it through! If you check the header, you'll see that it was sent Sunday night. In any case, thanks for the help (twice!) and it's working great now. Lyle {Original Message removed}
