- textual-for-each proc textual1 textual2 ...procedure
It is an error if proc does not accept as many arguments as the number of textual arguments passed to textual-for-each or does not accept characters as arguments.
The textual-for-each procedure applies proc element-wise to the characters of the textual arguments, going from left to right. If more than one textual argument is given and not all have the same length, then textual-for-each terminates when the shortest textual argument runs out.
