This is being with 2.6A for 16F1947

here is the error message:
ERROR: Macro NAND?TTL not found in macro file.Halting build on first failure as requested.
BUILD FAILED: Sun Feb 06 12:43:14 2011
and the offending code:
Code:
IF (LSH1 &/ HSP1) THEN LIMITHIT
I tried it with and without the (), still no joy.
LSH1 and HSP1 are both bits, so I thought this should work?

Any insight would be great here, thanks!!
