/* It's possible in Maxima to access individual characters by subscripts, but it's not the usual way.
|
|
Also, the result is "Lisp character", which cannot be used by other Maxima functions except cunlisp. The usual
|
|
way to access characters is charat, returning a "Maxima character" (actually a one characte string). With the latter,
|
|
it's impossible to modify a string in place, thus scopy is of little use. */
