I am trying to port some fortran source code from vax/vms to sun/unix.
The source code compiles on unix but doesn't link since randu couldn't
be found. I checked the code and found randu is referred as follows:

	call randu(i1,i2,u)

where i1,i2,and u weren't initialized before the call. I guess this
routine returns a random number in u and i1 and i2 are two seeds.

Obviously this routine is not f77 standard since I couldn't find it in
libF77.a. Instead, I found an equivalent function in libm.a called
rand which belongs to C library.

My question is how do you replace randu with rand? What is the range
of random number given by randu? Hope somebody who is familiar with
the vax version of fortran77 can shed me some light. Thanks.
