I am very new to the Amazing and Stunning world of PERL, so keep that in mind when I ask this question. I am trying to access a text file that I have created (owo.txt) and place the info into an array. I then need to extract and delete the duplicate entries. The order in which the program sorts the info is of little concern. What I have tried so far is below. This is placed after a loop in which the file is created. I get an error stating, "Modification of a read-only error at ... the line number is referring to 'undef @hsh{@ary};'". Could anyone help me on the mistake I am making. I appreciate it. Robert T Horn, CCNA $owo = "c:/scripts/owo.txt"; open (OWO, "+>$owo") or die $!; @ary = <OWO>; %hsh; undef @hsh{@ary}; @list = keys %hsh; print  @list;
