2. 8.23.4 Variables (Cent’d)
(4) Variable Representation
Each variable is represented in a variable number
that follows #.
a.
How to designate a number directly:
#i(i=l ,2,3, 4,...)
me
#lo
#130
#2000
b.
How to designate an expression as a variable
number:
# [ <expression>]
&22E&
#
[#loo]
# [#500 + 1]
# [#2012J
In the following description, variable #i may be
replaced with variable #[< expression >].
(5) Variable Reference
a.
The value that follows an address may be
replaced by a variable.
When < address> #i or <address> -#i is specified,
the value of the variable or its negative value
(complement, more exactly) is made the specified
value of the address .
Es!2P.k
#30= l.o;
#lol = 100. ;
#lo3 = 300. ;
#140 = o. 3 ;
G#30 X#lOl Z-#102 F#140 ;
The above specification is equivalent to the
specification below.
GO1 x1OO. Z-300. FO.3 ;
Notes:
1. Address / , 0, and N may not refer to varia-
bles .
Sample
/#8, N#100 . . . Error.
2. A variable number may not be replaced with
a variable.
Sample
##20 . . . Error.
#[ #20] . . . Correct.
Sample
(i) When #l = 45.2346
x#l ...
= X45.235 mm (for metric input)
(ii) When #2 = O. 255
F#2 ...=
FO. 26 (mm/rev)
(iii) When #3 = 5.37672
G04 P#3 ...
= G04 P5, 377 (see)
(iv) When #4 = 2.7236
M#4 . . . M03
GW. ..GO3
4. Value for each address should not exceed
the maximum programmable value.
5. The value that follows an address may be
replaced with <expression >.
(J. The constant without decimal point enclosed
in brackets [
] is assumed to have a decimal
point at its end.
(6) Undefined Variable
The value of an undefined variable is assumed to
be “blank. “ An undefined variable occurs in the
following situations:
a.
The local variable for which argument desig-
nation was not performed in macro call command.
b.
Common variables #100 through #149 at the
time of power–on and reset operations.
c. The local variables and common variables
for which the values were not written from MDI
panel.
3. When a variable is used as address data, the
values below the least significant digit are round-
