While Statements

The purpose of a while statement is to perform a repeated execution of a statement while a boolean expression yields TRUE. This boolean expression is checked before every execution of the statement sequence.

while_stmt  ::= WHILE boolean_expr DO stmt

Examples:

WHILE i>0 DO BEGIN
  i := i DIV 2;
  k := k+1
END;

WHILE (t <> NIL) AND (t^.key <> i) DO
  t := t^.left;
