Use this conversion instruction when you want to display or transfer BCD
values external to the processor.
Entering Parameters
•
Source – the address of the value to be converted to BCD. If the integer
value you enter is negative, the sign is ignored and the conversion occurs
as if the number were positive. The absolute value of the number is used
for conversion.
•
Destination – the address of the location to hold the result of the
conversion. With SLC 5/02 processors, the destination parameter can be
a word address in any data file, or it can be the math register, S:13 and
S:14. With fixed and SLC 5/01 processors, the destination can only be
the math register.
If the math register is the destination, 32,767 is the maximum value. If a
word address is used, 9999 is the maximum value.
