Unconditional Program Jumps - Siemens SINUMERIK 840Di sl Programming Manual

When assigning, write the character " = " after the address character. It is also possible to
have an assignment with a minus sign. A separate block is required for assignments to axis
addresses (traversing instructions).
Example:
N10 G0 X=R2 ;Assignment to the X axis
Arithmetic operations and functions
When operators/arithmetic functions are used, it is necessary to use conventional
mathematical notation. Machining priorities are set by parentheses. Otherwise, multiplication
and division take precedence over addition and subtraction. Degrees are used for the
trigonometrical functions.

Unconditional program jumps

Function
By default, main programs, subprograms, cycles and interrupt routines execute the blocks in
the sequence in which they were programmed. Program jumps can be used to modify this
sequence.
