Note The leftmost bit of each ASCII code is adjusted for parity.
Refer to page 115 for general precautions on operand data areas.
Flags ER (A50003): ASCII in S does not match parity designation.
Data in word S is not ASCII that can be converted.
Content of *DM word is not BCD when set for BCD.
Programming Example When CIO 000000 is ON in the following example, the ASCII data in D00010 is
converted to binary data and then output to D00300.
