Each variable expression must be less than 80 characters in length, including the

Numeric data can also be read into a variable, through the use of the

VARI1=READ1
All integer variables can be used within commands that require a real or integer value. For example, the
command requires real values for acceleration; therefore, the command
variable assignments are also legal; (e.g.,
Integer variables should be used whenever possible to allow faster math operation than numeric
variables (
).
VAR
Mapping inputs to a
variable: It is possible to map the binary value of a group of inputs to an integer
VARI
variable. For details, refer o the
Rule of Thumb for command value substitutions: If the command syntax shows that the command field
requires a real number (denoted by <r>) or an integer value (denoted by <i>, you can use the
substitution.
Example:
VARI1=2*3
D(VARI2)
Indirect Variables: Integer variables can be used indirectly. Only one level of indirection is possible (e.g.,
is not a legal command). The example below shows how indirect variables are used
VARI(VARI(VARIn))
to clear 50 variables (from 1 to 50).
Example:
VARI51 = 1
REPEAT
VARI(VARI51) = 0
VARI51 = VARI51 + 1 ; Increment counter
UNTIL (VARI51 = 51)
