While While While While
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 condition
:
command
(while
condition
is true)
: command (while condition is true)
:End
:
command
Repeat Repeat Repeat Repeat
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.
:Repeat condition
:
command
(until
condition
is true)
