Boolean Operand Description
BCD S, D Converts the 16 bits of binary data specified by "S" to
four digits of BCD data and stores it in "D".
Example: K100 → H100
BIN S, D Converts the four digits of BCD data specified by "S" to
16 bits of binary data and stores it in "D".
Example: H100 → K100
DBCD S, D Converts the 32 bits of binary data specified by (S+1,
S) to eight digits of BCD data and stores it in (D+1, D).
DBIN S, D Converts the eight digits of BCD data specified by
(S+1, S) to 32 bits of binary data and stores it in (D+1,
D).
INV D Inverts each bit of data of "D".
NEG D Inverts each bit of data of "D" and adds 1 (inverts the
sign).
DNEG D Inverts each bit of data of (D+1, D) and adds 1 (inverts
the sign).
ABS D Gives the absolute value of the data of "D".
DABS D Gives the absolute value of the data of (D+1, D).
EXT D Extends the 16 bits of data in "D" to 32 bits in (D+1, D). 3
DECO S, n, D Decodes part of the data of "S" and stores it in "D". The
part is specified by "n".
SEGT S, D Converts the data of "S" for use in a 7-segment display
and stores it in (D+1, D).
ENCO S, n, D Encodes part of the data of "S" and stores it in "D". The
part is specified by "n".
UNIT S, n, D The least significant digit of each of the "n" words of
data beginning at "S" are stored (united) in order in "D".
DIST S, n, D Each of the digits of the data of "S" are stored in
(distributed to) the least significant digits of the areas
beginning at "D".
ASC S, D Twelve characters of the character constants of "S" are
converted to ASCII code and stored in "D" to "D+5".
SRC S1, S2, S3 The data of "S1" is searched for in the areas in the
range "S2" to "S3" and the result is stored in DT90037
and DT90038.
DSRC S1, S2, S3 The data of (S1+1, S1) is searched for in the 32-bit
data designated by "S3", beginning from "S2", and the
result is stored in DT90037 and DT90038.
