What can be passed as a seed to this function ?

Is there a way to output the result of a function as text, to print the
value of rand for example ?

A PostScript pseudo random generator should generate
integer numbers in the range 1 to (2^31-1) .
IMO the value 0 is excluded (should be checked, can
depend on the implementation).
The seed is one of these numbers.
Because there is no fixed law for the implementation,
the results will differ e.g. for PDF and printers.
Therefore it's often recommended to program ones own
generator. A simple example is here:

The number can be printed
1. Define a font (page 7)
2. Define a string buffer buf (page 7)
3. x y moveto number buf cvs show
