+SysV User's should note that they have a similar program, called random.
+It's range of output values is restricted to 0..255 (the upper limit must
+be specified as a calling argument). If you need larger numbers, you
+can, of course, call random twice, multiply the result of the first
+call by 256, add the result of the second call, and take the whole thing
+modulo the largest number you want.

Be advised that the operations mentioned (multiplication, modulo) will,
in general, change the distribution of the random numbers.  That is, if you
started with uniformly distributed random numbers, then what you will
come out with will not be uniformly distributed.
