“Enter V, T and n: “ {“
:V: :T: :n:
“ {2 0} V } INPUT

Notice that you need to add the following piece of code after each of the
variable names V, T, and n, within the sub-program:
→STR “ ” +

→STR “ ” + )
within the sub-program (i.e., after variables T and n, respectively), all you need
to use is:
@ STR ‚Х ‚л ™+
