Functionality

Via REPEAT in part program block N150, the part program processing branches to the part program block N120

that is labeled START_1. This part program block and all of the following part program blocks (N130 and N140)

are repeated x number of times up to the part program block that contains the REPEATinstruction (N150). If P is

not specified, the part program section (N120 - N140) is repeated exactly once. After the last repetition, the part

program is continued with the part program block N160 following the REPEATinstruction.

N120 START_1: ...

N150 REPEAT START_1 P=n

Label search direction

The part program block marked with the Start label must come before the REPEATinstruction.
