Use this instruction when you want to convert BCD values to integer or
decimal values.
Entering Parameters
• Source – word address of the value in BCD to be converted to
integer/decimal. With SLC 5/02 processors, the source parameter can be
a word address in any data file, or it can be the math register, S:13. With
fixed and SLC 5/01 processors, the source can only be the math register.
If the math register is the source, 32,767 is the maximum value. If a word
address is used, 9999 is the maximum value.
• Destination – word address to contain the converted decimal/integer
value.
