Using subroutines

2.1
Function
In principle, a subroutine has the same structure as a parts program. It consists of NC blocks
with traversing and switching commands.
Basically, there is no difference between a main program and a subroutine. The subroutine
contains either machining operations or sequences of operations that are to be performed
several times.
