OK...I found out that bitfields aren't guarenteed to be packed in any way. Its implementation defined and so I'm screwed Smilie. That sucks too because it'd otherwise be such an elegant solution. I wonder why the specification left it open, if it were guarenteed it'd make doing bit manipulation so much easier than forcing me to manually mask off everything.

Performs packed-decimal addition. Compares two packed-decimal numbers. Converts an ASCII representation to packed-decimal. Converts a binary representation to packed-decimal. Converts a packed-decimal number to ASCII. Converts a packed-decimal number to binary. Performs packed-decimal division. Performs packed-decimal division (alternate routine). Performs packed-decimal multiplication. Performs a packed-decimal normalizing left shift. Performs a packed-decimal left shift. Performs a packed-decimal right shift. Performs packed-decimal subtraction. For all operations, the value returned in the variable to which the compcode argument points is one of the following values of type Result > 0 or operand1 > operand2 Result < 0 or operand1 < operand2 Result == 0 or operand1 == operand2 For all operations, the value returned in the variable to which the pacstatus argument points is one of the following values of type Their meanings are intended to be obvious: AUTHOR The HPPAC library was developed by HP.
