Especially it's suggestion to use the debugger. Roughly: > perl -dw prog.pl Loading DB routines from perl5db.pl Enter h or `h h' for help. main::(prog.pl:3): my $firstline; DB<1> c 123 main::(prog.pl:123): %hololoh # has just been loaded w/ first value +s DB<1> x %hololoh 0 HASH(0x3e5e54) ... [download] It's much easier when you can actually look at it with some initial values. (It even makes it easier to get your debugging print statements right.) p	[reply] [d/l]

Loading DB routines from perl5db.pl

Enter h or `h h' for help.

main::(prog.pl:3):    my $firstline;

  DB<1> c 123

main::(prog.pl:123):    %hololoh # has just been loaded w/ first value
+s

  DB<1> x %hololoh

0  HASH(0x3e5e54)
