Setting and Direct Transfer Variables
When using parametric programming with axis addresses and
expressions (including unary minus), the complete expression needs
to be in parenthesis. For example, X(-#151) is correct. X-#151 or
X-(#151) is not correct.
Variables are loaded or set when they display on the left side of an
equation. (That is, the left side of the equal sign).
Example 1: N200 #100 = 5.56
Variable #100 contains number 5.560000 until changed.
Example 2: N200 #100 = 25.4m
Variable #100 sets variable 100 to 25.4mm. Similarly, #100 = 5i sets
variable 100 to 5 inches. If neither "i" nor "m" is used when assigning
a variable, then the value of the variable is modal. For example, #100
= 8 sets variable #100 to 8 (no unit).
Example 3: N200 #100 = #20
Variable #100 contains the number held by #20 until changed.
Equating one variable with another is called a direct transfer.
When a direct transfer is requested, the variable on the
right side of the equation must contain a value.
Otherwise, the 3500i displays an error message (#nn not
defined).
