'"untyped"'
X has not yet been used yet at all; it can become a scalar or
- an array. For example:
+ an array. The typing could even conceivably differ from run
+ to run of the same program! For example:
BEGIN {
- print typeof(x) # x never used --> untyped
- mk_arr(x)
- print typeof(x) # x now an array --> array
+ print "initially, typeof(v) = ", typeof(v)

- function mk_arr(a) { a[1] = 1 }
+ function make_scalar(p, l) { l = p }
+
+ function make_array(p) { p[1] = 1 }
'isarray()' is meant for use in two circumstances. The first is when
traversing a multidimensional array: you can test if an element is
