If this is a procedure you will need to do on the same data set more
than once, consider using the randomize statement before using rnd(1)
... I can't speak for MapBasic, but in the past with other languages
have had trouble getting the same result every time I ran a procedure.
I assume the randomize statement is available in MapBasic to address
just this kind of problem.

Hello,
I have a table of 99769 records. I want to select out 200 of these at
random. Is there a way of doing this automatically in MapInfo rather
than generating a random number list and picking each record out
manually? I am using version 8. The table has a column of unique
numbers entitled ID.
Thanks for any help
