13 The function param(n) can be used only within the body of the

16 If that function is f()
18 [[ which may have been defined with named arguments as in f(x,y,z))
20 and either the number of arguments or the value of an argument

26 and the value of the n-th argument by:
30 Note that unlike the argv() builtin, param(1) is the 1st parameter

36 ;; for (n = 1; n <= param(0); n++)
41 ; print f(), f(1), f(1,2), f(1,2,3)
