Post by thread:[PIC]: Comments in MPLAB

[PIC seems to be the best tag for this]... Is there any way to comment out a block of code in MPLAB, w/o dropping a semi-colon on every single line? Could not find an answer to this in the MPLAB users' guide. Cheers, -Neil. -- http://www.piclist.com#nomail Going offline?

Immediately before the code I want to eliminate I insert the line: if 0 When I want to end the 'commenting', I insert the line: endif Works like a champ.

I do this with conditional assembly. For example, to comment out your original message, I'd do if 0 On Wed, 19 Jun 2002 12:24:54 -0500 Pic Dude <EraseMEpicdudespam_OUTTakeThisOuTAVN-TECH.COM> writes: {Quote hidden}> [PIC seems to be the best tag for this]... > > Is there any way to comment out a block of code in MPLAB, w/o > dropping a semi-colon on every single line?

I use "ifdef" or "ifndef" with a label that I *know* is undefined (not used anywhere else) and describes the block of code you are commenting out: ; #define SomeLabelThatDescribesThisBlock ;un-comment this line to enable the block of code ifdef SomeLabelThatDescribesThisBlock code goes here ... more code endif You now have 2 choices: remove the ifdef and endif around the block or simply remove the semi-colon at the front of the #define line. I'm sure that there are other techniques but this is what I use. dwayne -- Dwayne Reid <RemoveMEdwaynerTakeThisOuTplanet.eon.net> Trinity Electronics Systems Ltd Edmonton, AB, CANADA (780) 489-3199 voice (780) 487-6397 fax Celebrating 18 years of Engineering Innovation (1984 - 2002) .-. .-. .-. .-. .-. .-. .-. .-. .-. .- `-' `-' `-' `-' `-' `-' `-' `-' `-' Do NOT send unsolicited commercial email to this email address.

Something nobody mentioned yet is just to put a goto block_end (etc) before the code block you want to disable. This has the added advantage of still assembling ALL the code, so code and tables that cross code pages etc will still remain in the same positions in memory, something that really could catch a beginning programmer who is mainly disabling large blocks of their code to test things. -Roman Harold M Hallikainen wrote: {Quote hidden}> > I do this with conditional assembly.

Well when using this quick-and-nasty technique I actually comment out the first inst of the block and use the goto instead. But i'm sure you knew that already. :o) -Roman -- http://www.piclist.com hint: PICList Posts must start with ONE topic: [PIC]:,[SX]:,[AVR]: ->uP ONLY! [EE]:,[OT]: ->Other [BUY]:,[AD]: ->Ads
