2 Instruction Descriptions
The data type of data format number Format is enumerated type _eBCD_FORMAT. Select one of the
following: _BCD0, _BCD1, _BCD2, or _BCD3. The sign specification in the upper four bits of In
depends on the BCD format number. The data format examples shown below use WORD data for In.
Format = _BCD0
Valid range of In: −999 to 999 (BCD)
15 1211 8 7
