Conversion Instructions Section 3-11
Operands C: Control Word
Specifies the signed BCD format. C must be 0000 to 0003.
S: First Source Word
Source words S+1 and S contain the double signed binary data to be con-
verted. Their content must be within the valid range of the BCD format speci-
fied in C.
D: First destination word
Destination words D+1 and D contain the converted double signed BCD data.
See the description section below for an explanation of the BCD formats.
Operand Specifications
Description BDSL(473) converts double signed binary data to double signed BCD data.
First the double signed binary data in S+1 and S is checked to verify that it is
within the valid range for the signed BCD format specified in the control word
(C). If the source data is correct, the double signed binary data in S+1 and S
is converted to double signed BCD and output to D+1 and D. If the source
data is incorrect, the Error Flag will be turned ON and the instruction will not
be executed.
Setting Allowed values for S+1 and S
C=0000 FF67 6981 to FFFF FFFF or 0000 0000 to 0098 967F
C=0001 FB3B 4C01 to FFFF FFFF or 0000 0000 to 04C4 B3FF
C=0002 FF67 6981 to FFFF FFFF or 0000 0000 to 05F5 E0FF
C=0003 FECE D301 to FFFF FFFF or 0000 0000 to 05F5 E0FF
