#460 Seed in Random() BIF

[Felix Hofmann]

The only qualification in the doc & TRL2 for seed is that it must be a whole number.

the following snippet demonstrates the problem ....

numeric digits 200
do i=25 to 100; s=2**i; say i
r=random(,,s)
end

the output follows .....

25
26
27
28
29
30
31
3 +++ r=random(,,s)
Error 40 running "C:\rand", line 3: Incorrect call to routine
Error 40.12: RANDOM argument 3 must be a whole number; found "2147483648"

I think the limit here is 999999999 (the platform limit for whole numbers)

[Felix Hofmann]

Hi Walter,

thanks for your response

please note that 2**30 = 1,073,741,824 was acceptable

and this is greater than 999,999,999

cheers

Interesting:

y=2**30
say y
say random(,,y)

ooRexx does what I expect:
E:>rexx rat
1.07374182E+9
3 - say random(,,y)
Error 40 running E:\rat.rex line 3: Incorrect call to routine
Error 40.12: RANDOM argument 3 must be a whole number; found "1.07374182E+9"

So does CMS:
