Program section repeats
A program section repeat is entered like a subprogram. The end of
the program section is identified simply by the command to repeat
the section.
Label 0 is therefore not set.
CALL LBL block for a program section repeat
Example of a call label block: CALL L 1 R10 / 10 .
The two numbers with the slash between them indicate that this is
a program section repeat. The number in front of the slash is the
number of repetitions you programmed. The number behind the
slash is the number of repetitions remaining to be run.
