Offsets
All tool work offsets can be read and set within a macro expression to allow the
coordinates to be preset to approximate locations, or set coordinates to val-
ues based upon results of skip signal locations and calculations. When any of
offsets are read, the interpretation lookahead queue is stopped until that block
is executed.

All variables are referenced with a pound sign (#) followed by a positive num-
ber: #1, #101, and #501.
Variables are decimal values that are represented as oating point numbers.
If a variable has never been used, it can take on a special “undened” value.
This indicates that it has not been used. A variable can be set to undened with
the special variable #0. #0 has the value of undened or 0.0 depending on the
context it is used in. Indirect references to variables can be accomplished by
enclosing the variable number in brackets: #[<Expression>]
The expression is evaluated and the result becomes the variable accessed.
For example:
#1=3;
#[#1]=3.5 + #1;
This sets the variable #3 to the value 6.5.
Variables can be used in place of G-code address where “address” refers to
the letters A-Z.
