Alternative syntax

A dollar command can be used to alter the for statement syntax.  Namely, Endfor is introduced as a keyword when $Onend is active and becomes illegal upon use of $Offend.  When active, Endfor ends the For statement.  The dollar command option is employed using the syntax

$Offend

or

$Onend

Setting the $Onend dollar command option will make the alternative syntax valid, but makes the standard syntax invalid.
