comm command bug while using with Tilda delimited files

[Anand Ramamoorthy]

This is the first time I'm having issues with "comm" command on an HP-UX Unix 
box (Model: 9000/800, Release: B11.11)
 
I'm trying to compare two files that are "~" delimited.
 
File 1
--------
1~10
5~30
55~40
6~20
 
 
File 2
--------
1~20
5~35
55~40
7~27
 
Now I'm trying to get the common records of the above files, I sould be getting 
55~40 which is there in both files. But I get none as output. But if I use "," 
as delimiter instead of "~", then it works. Dont know whether "~" is a special 
char for comm command.
 
 
Here is how I use comm command.
 
comm -12 file1 file2
 
 
Thanks in advance for any help you can provide me.
 
Regards,
Anand.
