GAS - \@ in macros and labels

[<kieft_brian@si.com>]

I'm having a little trouble with specifying labels inside of two different
macros using the \@ variable. See the following...

 .MACRO tableHdr    someArgs
A_\@:
     .DC.W  (B_\@ - A_\@)   
    stuff....

 .ENDM

 .MACRO tableEnd    someArgs
B_\@:
 .ENDM

Unfortunately the number produced by \@ will never be in sync between the two
macros due to the fact that a new macro call will increment the counter (not to
mention that there may be some other macros called in between Hdr and End).

So I attempted to resolve the situation by creating my own variable...

.MACRO  tableHdr    someArgs
.SET    CMD_NUM,\@
A_CMD_NUM:
     .DC.W  (B_CMD_NUM - A_CMD_NUM)     
    stuff....

 .ENDM

 .MACRO tableEnd    someArgs
B_CMD_NUM:
 .ENDM


Unfortunately GAS sees this as literal text and throws a bunch of "symbol
already defined" errors. Any ideas on how to make the CMD_NUM appear as its
value in a label? Thanks,

Brian
