RandomSeed with Maximum parameter

RandomSeed(Value[, Maximum])
Note: each times a program start, a new seed is generated ..
If Random() always uses the same seed then this additional parameter for RandomSeed() would be nice.

what would be the use of it?
the maximum is a parameter of Random, not of the Seed...
...
one thing I would like to see for Random() is several Rows with different Seeds...

I believe RandomSeed returns a long (or integer?). The Maximum parameter would provide an alternative upper-bounds for the return value. Or maybe I'm misunderstanding the function.

RandomSeed() ensures that you always get the same numbers, even when you restart your program.
On first program start, you get the numbers
on second start, you get the numbers
and so on. The third start gives you the same numbers again. A maximum parameter for
RandomSeed() is nonsense, you can use the maximum parameter provided by
Random(). This parameter is independent from
RandomSeed().
Btw,
Random() returns a long.

Actually it's an integer.
freak, regarding returntype of Random(), wrote:Note that you only get 64bits on x64 as the returntype is integer.

the Seed is independent from the Range of the later called Random function.
this code:
Code: Select all
RandomSeed( 42 )
Debug Random( 4711 )
Debug Random( 4711 )
Debug Random( 10 )
Debug Random( 4711 )
always produces
866
2197
4
2483
and so it always should as a 32bit exe.
... wonder if it returns the same as a 64bit exe.

No disrepect intended, Sir.
I mentioned that to clarify that you are not limited to a Long value, except when compiling for 32-bit.
