Program section repetition

Function
Program section repetition allows you to repeat existing program sections within a program
in any order. The block or program sections to be repeated are identified by labels.
For more information on labels, please see:

Programming repeat block
LABEL: xxx
yyy
REPEATB LABEL P=n
Zzz
The program line identified by a label is repeated P=n times. If P is not specified, the
program section is repeated exactly once. After the last repetition, the program is continued
at the line zzz following the REPEATB line.
The 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 in this
direction, the search continues toward the end of the program.

executed again on each repetition. If P is not specified, the program section is repeated
exactly once. After the last repetition, the program is continued at the line zzz following the
REPEAT line.
