    Are high() and low() built into MPLAB or are they your own macros?

    Hey Mr. RB,

    They are macros, high will capture the MSByte of a 16bit address and low will capture the LSByte. One handy use is to store the PCLATH value of a label by using the "high".

    Roman, there's also an 'upper()' operator to capture the b23..b16 portion of the constant operand. So, a matched set of sorts for setting TBLPTRL, H, and U (grin)...

    Have fun, Mike
