Description When
the
execution condition is OFF
, BINL(58) is not executed. When the exe
-
cution condition is ON, BINL(58) converts an eight-digit number in S and S+1
into 32-bit binary data, and outputs the converted data to R and R+1.

Binary
Flags ER: The contents of S and/or S+1 words are not BCD.
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 result is zero.

Description BCD(24) converts the binary (hexadecimal) content of S into the numerically
equivalent BCD bits, and outputs the BCD bits to R. Only the content of R is
changed; the content of S is left unchanged.

BCD(24)
can be used to convert binary to BCD so that displays
on the Program
-
ming Console or any other programming device will appear in decimal rather
than
hexadecimal. It can also be used to convert to BCD to perform BCD
arith
-
metic
operations rather than binary arithmetic operations, e.g., when BCD and
binary values must be added.
Note If
the content of S exceeds 270F
, the converted result would exceed 9999 and
BCD(24)
will not be executed. When the instruction is not executed, the content
of R remains unchanged.
