Split question

[Scott and Kristin Seitz]

I have a delimited text file with a vertical bar (|) as the column delimiter.  When I 
execute the following statement...

@Line = split(/\|/, $_);

...I get the expected results.

When I execute the following...

$CharSep="\|";
@Line = split(/$CharSep/, $_);

...the file seems to break at every character.  Instead of @Line[0]="Date", 
@Line[0]="D", @Line[1]="a", @Line[2]="t",@Line[3]...well, you get the idea.

What do I need to add to the second bit of code to make it work?
