Hi,
The bug comes from the unidentification of seed in
the first randomu call of every call of test.pro
The solution is to save the value of seed between
different calls of test.pro
Or you might use common block (Ok, David, I know...) or
a system variable:

PRO test
common seed_for_test,seed

x= RANDOMU(seed,1)
y= RANDOMU(seed,4)
PRINT,'x',x
PRINT,'y',y

RETURN

END

or

PRO test
defsysv,'!seed',EXISTS = seed_exists
if seed_exists then seed = !seed

x= RANDOMU(seed,1)
y= RANDOMU(seed,4)

defsysv,'!seed',seed

PRINT,'x',x
PRINT,'y',y

RETURN

END
