Main group 6/subgroup 6: Logical procedures
@660 <Var> <Const>
A bit (0 to 7) is defined by the constant <Const>; this bit is to be deleted in the bit
pattern defined by <Var>.
Example:
R60 = 01100111
@660 R60 K6
@661 <Var> <Const>
The constant <Const> defines a bit (0 to 7) which is to be set to "1" by the bit pattern
defined by <Var>.
Example:
R70 = 00000000
@661 R70 K2
Main group 6/subgroup 7: Boolean comparison assignments
@671 <Var 1> <Var 2> <Value>
If the numerical values defined in <Var 2> and <Value > are equal, the Boolean
variable <Var 1> is set to "1".
Example:
R50 = 11001100
@671 R51 R50
@672 <Var 1> <Var 2> <Value>
If the numerical variables defined in <Var 2> and <Value> are not equal, the Boolean
variable <Var 1> is set to "1".
@673 <Var 1> <Var 2> <Value>
If the numerical value define in <Var 2> is greater than that in <Value>, the Boolean
variable <Var 1> is set to "1".
@674 <Var 1> <Var 2> <Value>
If the numerical value defined in <Var 2> is greater than or equal to that in <Value>,
the Boolean variable <Var 1> is set to "1".
@675 <Var 1> <Var 2> <Value>
If the numerical value defined in <Var 2> is less than that in <Value>, the Boolean
variable <Var 1> is set to "1".
@676 <Var 1> <Var 2> <Value>
If the numerical value defined in <Var 2> is less than or equal to that in <Value>, the
Boolean variable <Var 1> is set to "1".
11–42
Bit No. 6 in the pattern variable is deleted.
R60 has the contents 00100111.
Bit No.2 in the pattern variable is set.
R70 has the contents 00000100.
K11001100 Since R50 is equal to the bit pattern, R51 is set to
"1".
