Entering and calling program section repeats

A program section repeat is entered like a subprogram. Since the
end of the program section is identified simply by the command to
repeat the section (

CALL LBL

), label 0 is not set.

CALL LBL

block with a program section repeat

The screen displays (for example):

The two numbers with the slash between them indicate that this is
a program section repeat.

tered.

The number behind the slash is the number of repeats remaining
to be performed.
