Limitations D and D+15 must be in the same data area.
C must be between #0000 and #0015.
Description When the execution condition is OFF, COLM(64) is not executed. When the
execution condition is ON, COLM(64) copies the 16 bits of word S (00 to 15) to
the column of bits, C, of the 16-word set (D to D+15).

Flags ER: The bit designator C is not BCD, or it is specifying a non-existent bit (i.e.,
bit specification must be between 00 and 15).
Indirectly addressed DM word is non-existent. (Content of DM word is
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the content of S is zero; otherwise OFF.
Example The following example shows how to use COLM(64) to move the contents of
word DM 0100 (00 to 15) to bit column 15 of the set (DM 0200 to DM 0215).
