- (textual-copy textual [start end]) → textprocedure
Returns a text containing the characters of textual beginning with index start (inclusive) and ending with index end (exclusive).
Unlike subtext and subtextual, the result of textual-copy never shares substructures that would retain characters or sequences of characters that are substructures of its first argument or previously allocated objects.
If textual-copy returns an empty text, that empty text may be eq? or eqv? to the text returned by (text). If the text returned by textual-copy is non-empty, then it is not eqv? to any previously extant object.
