Designation and function of <blank> is classified
in the following two versions A and B. The
control is set for either version.
Switching from

Variable <blank>
is commanded
in the condition
of EQ and NE.
Others
Version A
No conception
of #o.
‘Commanding *O
causes alarm.
‘Where #2 is

mand #3 = n2.
means #3 = O.

to command G C

<Blank> in the replacement described
above is treated as “O.”
‘Condition IF ?3 GE Z2 is established
when #2 and P3 are <blank>, or

2.8,23.5 Operation Commands
Various operations can be performed between
variables and between variables and constants .
The operation expression is represented in the
form of #i = <expression> , in which < expression>
is a general arithmetic operational expression pro-
duced by combining variables and constants with
operators and functions. The available operat-
ions and functions are as follows. Instead of
fi and #k, constants may be used.
(1) Variable Definition and Replacement
#i = #j . . . definition, replacement.
(2) Add-Type Operations
#i. #j+#k . . .
#i=#j -#k . . .
#i=#j OR#k . . .
#i=#j XOR #k...
(3) Multiply-Type
#i=#j *#k . . .
#i=#j /#k . . .
#i=#j AND #k...
Sum.
Difference.
Logical sum (for each of
32 bits) .
Exclusive logical sum
(for each of 32 bits).
Operations
Product.
Quotient.
Logical product
(f& each of 32 bits) .
Note: In OR, XOR , or AND operation, the
variable value (or constant) is converted into
the binary 32–bit equivalent and the operation
is performed on each bit.
