Post by thread:[PIC]: labeling an indivdual bit in MPASM

Is there a directive in MPASM, equivelent to CBLOCK but that labels indivdual bits insteed of whole bites? I need 3 or 4 bits to use as flags. -- Seth Fischer Auckland, New Zealand spam_OUTfischersTakeThisOuTxtra.co.nz -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.

You can "label" a flag with: #define flag_afu gfl0,0 And then use it like BSF flag_afu However, this doesn't help with allocating the flag bits and making sure that another flag doesn't use the same bit, etc. I run all my MPASM source code thru a preprocessor that, among other things, implements a /FLAG directive. This allocates individual flag bits in variables GFL0, GFL1, ... GFLn. An assembly variable is set to the number of GFLn variables required so that these can be allocated later. ******************************************************************** Olin Lathrop, embedded systems consultant in Littleton Massachusetts (978) 742-9014, olinKILLspamembedinc.com, http://www.embedinc.com -- http://www.piclist.com hint: The list server can filter out subtopics (like ads or off topics) for you.
