creating multiple variables in loop

[Sonal Singhal]

Simple question, I hope... I am looping through a set of commands, and each
time, I want to create a unique array with a tag representing the loop
number.

for (my $j = 1; $j < $#start_points; $j++){
        if ( abs($start_points[0] - $start_points[$j]) > 1999) {
            my @{start_points."$n"} = @start_points[$j...$#start_points];
            my @{end_points."$n"} = @end_points[$j...$#start_points];
            }
        }

I would hope this would give me 'n' arrays: @start_points0, @start_points1,
etc.  But this isn't working.
ERROR MESSAGE: Can't declare array dereference in my at
/Users/s/Desktop/shorttest.pl line 17, near "} ="

I know I can do an array of arrays but that doesn't work well for the rest
of my program.

Any help would be appreciated!
