While performs a group of
commands
while
condition
is
true.
condition
is frequently a relational test (Chapter 2).
condition
is tested when
While is encountered. If
condition
is true (nonzero), the program executes a group
of
commands
.
End signifies the end of the group. When
condition
is false (zero), the program executes each
command
following
End. While instructions can be nested.
:While

Program Output
Repeat repeats a group of
commands
until
condition
is
true (nonzero). It is similar to
While, but
condition
is tested
when
End is encountered; therefore, the group of
commands
is always executed at least once.
Repeat
instructions can be nested.
