A part program section after a start label
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
REPEAT
instruction (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
REPEAT
instruction.
Note
Label search direction
The part program block identified by the label can appear before or after the REPEATB
statement. The search initially commences toward the start of the program. If the label is not
found, a search is made in the direction of the program end.
