CREATING A PROGRAM
Program structure
(SOFT V02.0X)

The CNC program may consist of several subroutines and the body
of the program.
Local subroutines
A subroutine is a set of blocks that, once properly identified, may be
called upon several times from another subroutine or from the
program body.
Programming subroutines is optional and they must be defined before
the program body. Subroutines are normally used for defining a bunch
of operations or movements that are repeated several times
throughout the program.
The beginning of a subroutine is defined by "%L<name>", where
<name> may be up to 14 characters long and consist of uppercase
and lowercase letters as well as numbers (no blank spaces are
allowed). Subroutine call is case sensitive, the name must be written
exactly as it has been defined. . The end of the subroutine is defined
with M17, M29 or #RET.
