Procedure Rotate Help

[SucreTeen123]

Write and test a procedure subprogram called rotate which
will rotate the integer values of three parameters. If the
parameters A, B, and C originally had values 1 2 3 before the
operation of the procedure, then afterwards the values would
be 3 1 2.

I based the rotate program on this one:

procedure swap (x, y : string)
put x
put y
end swap
swap ("Sweet" , "Cake")

but when I try to do the rotate one it doesn't work! Can someone please explain to me what I am doing wrong?
procedure rotate (a, b, c : string)
put a
put b
put c
end rotate
rotate ("3", "4", "1")
