I'm running Perl 3.0 pl 8 on Sun-3s.

The following script produces the unexpected output -1.

#!/usr/hydrogen/gnu/bin/perl
@array = (0,1,2,3,4,5,6);
# $#array;  # uncomment this line for expected behaviour
$#array -= 2;
print "elements in array -- ",$#array,"\n";

If the indicated line is uncommented, the script behaves as expected.

Feel free to let me know if I'm doing something stupid or I had my
eyes closed while reading the manual.
