Re: Finding Minimum Value

[hdb]

In addition to what was said above, $grade{$id,$exam} does not do what you expect. Try $grade{$id}{$exam} to create a two-dimensional data structure.

update

IMHO that's a misnomer, cause its a multidim HASH emulation.

May be a case where originally a "associative array" was meant, but the terminology should be consistent.

It might work. See $; in perlvar.
