I must be still confused, if I use indexes instead of literal pointers, if the data is written with a different order I would get different results then? I am reading http://perldoc.perl.org/perllol.html and http://perldoc.perl.org/perldsc.html and have made some examples but there must be a way to make sure I am reading the data I want?
Send me another nudge :) Thanks! jlc -----Original Message----- From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] On Behalf Of Tom Phoenix Sent: October-19-07 12:19 PM To: Joseph L.

But the print statement, after using 'TextHere' as a hash key, is trying to access a hash and then an array. That is to say, you're asking for $workspace->{TextHere}->{content}->[0] but $workspace->{TextHere} is a reference to an array, so you need to de-reference it as an array. The next element should be an array index in square brackets, but you've got a hash key in curly braces: $workspace->{TextHere}->{content} Do you see how to fix it now?
