Is matter of order?..(UPDATE: evidently not seen the anonym's answer above..) `BEGIN{($path = $0) =~ s[[\\/][^\\/]+$][];} BEGIN{ use lib $path;}` [download] gives no error.

`BEGIN{($path = $0) =~ s[[\\/][^\\/]+$][];} BEGIN{ use lib $path;}` [download] use implies `BEGIN`, so that `BEGIN` should not be needed. There is a simpler way: `use lib do { ... }`, shown in Re^2: Calculations before using lib;. Combined with the `s///r` syntax from newer perls, this can be collapsed to `use lib do { $0=~s[[\\/][^\\/]+$][]r };`. Also note that `$0` may not always contain an absolute path: `>cat tmp.pl #!/usr/bin/perl use strict; use warnings; print "$0\n"; >chmod +x tmp.pl >perl tmp.pl tmp.pl >perl ./tmp.pl ./tmp.pl >perl /tmp/tmp.pl /tmp/tmp.pl >./tmp.pl ./tmp.pl >tmp.pl ./tmp.pl >` [download] Alexander -- Today I will gladly share my knowledge and experience, for there are no sweeter words than "I told you so". ;-)	[reply] [d/l] [select]
