Operation Notes
This command terminates a conditional block that begins with a WHILE command. The
WHILE and ENDWHILE commands constitute a WHILE block. The WHILE command evaluates
an expression, and so long as that expression evaluates as true, the command(s) between
WHILE and ENDWHILE are executed. If the expression evaluates as false, execution of the
WHILE block ceases and execution passes to the command following ENDWHILE. Execution
terminates if any command not protected by a preceding CONTINUE causes an error.
