Randie:

The Carry flag is in bit 0 of the STATUS register (register 3), so
you can clear it with:

    BCF 3,0

or, if you've defined the appropriate symbols in your source code:

    BCF STATUS,CARRY

or, if you're using MPASM, you can just do the following:

    CLRC

which is automatically translated by the assembler to "BCF 3,0".
