Routine Description:

    Standard printf function with a subset of formating features supported.

    Currently handles

     %d, %ld - signed short, signed long
     %u, %lu - unsigned short, unsigned long
     %c, %s  - character, string
     %x, %lx - unsigned print in hex, unsigned long print in hex

    Does not do:

     - field width specification
     - floating point.

Arguments:

    cp - pointer to the format string, text string.


Returns:
