Guessing this kind of thing has been used by many COBOL programmers.
There is a TABLE of 10-digit numbers.
User enters (ACCEPT) how many such numbers they require.
an ARRAY of 5 x 2-digit RANDOM numbers is loaded.
That ARRAY ( 10-digits ) will be added to the TABLE.
Seems easy enough, but DUPLICATES in an ARRAY need to be prevented.
I suspect (hope) there might be an algorithm that will cope
with this in one go ???
Thanks in advance.
