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)

:End

:command

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.

:Repeat condition

:command (until condition is true)

:End

:command
