Since you only use the parameter once, it's cheaper to just reference it as $ARGV[0] pop it inline rather than assign it to anything.
@b=(0,1);push@b,$b[-2]+$b[-1]for 2..pop;print$b[-2]
You can save fourteen more strokes (and, irrelevantly, memory) by not using an array and using convoluted scalar assignment with a variable that is pre-initialized:
$b=1;$?=($b+=$?)-$?for 2..pop;print$?

[Marshall]: stevieb wish you well with water problems, my water was off all day Monday for repairs. Any more progress on .exe info problem?.
[stevieb]: Marshall: no. I commented on the thread yesterday. Visual Studio updates the tags ok, but corrupts the exe
[stevieb]: I advised the OP that a possible workaround would be to add a version function/flag that displays the required copyright/license info instead
[Marshall]: Darn! I'll look at the thread. Must not be updatinga byte count somewhere. The .exe format is a complex critter.
[stevieb]: that way, it's still "hard coded" into the exe at least, despite not being visible via Properties
[Marshall]: I also looked into PerlApp from Active State, but they don't sell their Dev Kit independent of a very expensive ($1,200) per year license anymore.
