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 Bit No. 6 in the pattern variable is deleted.
R60 has the contents 00100111.
@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 Bit No.2 in the pattern variable is set.
R70 has the contents 00000100.

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 K11001100 Since R50 is equal to the bit pattern, R51 is set to
”1”.
@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“.
