    I have no examples, it has been years.

    To convert to characters, do a STD, UNPK, and TR.
 Multiple UNPK's may be needed.  Last byte of the UNPK will be garbage.
 The TR should point to 240 bytes before table CL16'0123456789ABCDEF'.

    OR,

    If you need to convert to decimal numbers, multiply by 1,000,000,000.
 Do a STD.  Separate the whole number from the sign, fractions, etc.
 Load the whole number into a general purpose register.
 CVD, UNPK, and put the decimal point back in.
