while
WHILE tfexpression instructionlist (library procedure)
command. Repeatedly evaluates the "instructionlist" as long as the
evaluated "tfexpression" remains TRUE. Evaluates the first input
first, so the "instructionlist" may never be run at all. The
"tfexpression" must be an expressionlist whose value when evaluated
is TRUE or FALSE.
