7-20-3 DOUBLE BCD-TO-DOUBLE BINARY – BINL(58)

ER: The content of S is 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.

R
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.
DM 6144 to DM 6655 cannot be used for R.
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.
Indirectly addressed DM word is non-existent. (Content of *DM word is
ER:
not BCD, or the DM area boundary has been exceeded.)
EQ: ON when the result is zero.
