Structure of a DIN 66025 program

The DIN 66025 program consists of individual motion blocks. The block number is located at the beginning of each block.

['%' <Programmname>]
<Satz>{<Satz>}

The blocks can be structured as follows:

N<block number> G<expression> <G code words>
N<block number> <G code words> (the G<expression> of the previous block apply)
N<block number> M<expression> <G code words>
N<block number> <subroutine name> ( <ActualParamList> )
Additional block structures for subroutines:
- SUBPROGRAM <Name> {<FormalParamList>} <RESTORE_OPT>
- N<block number> RETURN
- END_SUBPROGRAM

Example

Path from two lines and an arc, followed by a subroutine call
