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 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)
