Arithmetic Commands
By performing general
arithmetic
operations
in which local
variables,
common variables,
system
variables, and constants
are
-combined with
operations or functions,
it is possible
to
substitute the results of
operation
for a given variable. Using variables in these arithmetic operations means
reading the required data from the internal variable data
area,
and
substituting the results of operation means writing the operation result data
into
the internal variable
data area.
The write cycle is completed when the
execution of one block is completed. The basic formula of arithmetic
operation is
#i = (expression).
:
The following operations and
functions
can
be used:
(1) Definition
or replacement
of
variable
#i=#j Definition or replacement
#i=# C#j = #kl Indirect specification
(2) Add calculations
#i
=
#j +
#k
Sum
Difference
#i=#jOR#k Logical
sum (for
each bit in binary 32
bits)
Exclusive logical sum
(for
each bit in
binary
32 bits)
#i=#j.\OR#k
(3) Multiply
calculations
Product Si = »j*#k
Quotient #i=#j
#k
#i=#jAND#k Logical product (for each bit in binary 32 bits)
Residue (For
#j and ffk. the residue is
obtained after being rounded
to
an integer.
If #j is negative,
#i also becomes
negative.)
#i
