Converse to the V AL variable, substitutes the numerical
variable I as if it were a string for string variable N$.
Substitutes the numerical string of string variable N$ as if
it were a number for variable I.
Substitutes the character length (character number) of
string variable X$ for variable LX.
Substitutes the sum of the character length of string
