~~Title: Val~~ Val && var && Value of the named argument. && varname && string && Name of the argument. && [deref] && bool && Dereference argument value. Returns the value of a variable; //varname// is provided as a quoted string. This is useful for variables which contain characters that would confuse the Evaluator's parser (e.g. if the name begins with a number). //Example:// flag = Val("35mmfocallength"); // get value of the 35mmfocallength field If the //deref// parameter is set to **true**, it causes the variable (if any) named by the first value to be dereferenced and returns its value instead of the value of the named value. For example, a = "b"; b = "c"; Output(Val(a)); // -> "b" Output(Val(a, true)); // -> "c"
