9.9.11.3 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 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.
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.
Syntax:
REPEATB <Label> [P=n]
Labe
l
Start label to which the instruction: REPEAT branches
Type: String
P
Number of repetitions
?{}?
n
Number of repetitions
Type: Integer
