Conversion Instructions Section 5-19
If the parity of the ASCII code in S does not agree with the parity specified in
Di, the ER Flag (SR 25503) will be turned ON and the instruction will not be
executed.
Flags ER: Incorrect digit designator, or data area for destination exceeded.
Indirectly addressed DM word is non-existent. (Content of
∗DM word
is not BCD, or the DM area boundary has been exceeded.)
Example In the following example, the 2
nd
byte of LR 10 and the 1
st
byte of LR 11 are
converted to hexadecimal values and those values are written to the first and
second bytes of IR 010.

Limitations This instruction is available in the CQM1 only.
P1 through P1+3 must be in the same data area.
DM 6144 to DM 6655 cannot be used for P1 through P1+3 or R.
Description SCL(66) is used to linearly convert a 4-digit hexadecimal value to a 4-digit
BCD value. Unlike BCD(24), which converts a 4-digit hexadecimal value to its
4-digit BCD equivalent (S
hex
→ S
BCD
), SCL(66) can convert the hexadecimal
value according to a specified linear relationship. The conversion line is
defined by two points specified in the parameter words P1 to P1+3.
When the execution condition is OFF, SCL(66) is not executed. When the exe-
cution condition is ON, SCL(66) converts the 4-digit hexadecimal value in S to
the 4-digit BCD value on the line defined by points (P1, P1+1) and (P1+2,
P1+3) and places the results in R. The results is rounded off to the nearest
