Available properties: alpha: compares to all alpha characters nonspace: compares to all non-space chars (tab is not a space) all: compares to all chars Examples: //echo -a $caps(ab CD12) //echo -a $caps(ab CD12).alpha //echo -a $caps(ab CD12).nonspace //echo -a $caps(ab CD12).all / Code: alias caps { var %caps = $regex($$1,/[A-Z]/g), %type = alpha nonspace all if (!$prop) return %caps if (!$istok(%type,$prop,32)) return Bad property return $calc(100%caps /$regex($1,/ $gettok([a-z];[^ ];.,$findtok(%type,$prop,1,32),59) /gisx))) }
