REPEAT <Start_Label> <End_Label> [P=n]

A part program section between a Start label and the key word: ENDLABEL

Functionality

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

that is labeled START_1 with a start label. This part program block and all the part program blocks up to and

including the part program block marked with the key word ENDLABEL (N140) are repeated x number of times. 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 N170 following the REPEATinstruction.

N120 START_1: ...

N140 ENDLABEL: ...

N160 REPEAT START_1 END_1 P=n

Label search direction

The program section marked with the Start and End labels can come before or after the

REPEATinstruction. The search initially commences toward the start of the program. If the

Start label is not found, a search is made in the direction of the program end.

If no keyword ENDLABEL is located between the Start label and the REPEAT instruction, the

part program section from the Start label to the REPEAT instruction is repeated.
