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 exe-
cution 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).
