Randomly Generated Variables

I am relatively new to this generation of variables in ASP. I am unable to proceed from here. Can somebody advise?

Challenge :

I get number of participants in an exam, from a sql statement and stored into a variable called headcount.

For j=1 To CLng(headcount)
Eval Execute("student" & j & "=" & 0)
