Please use <code/> tags for code AND DATA, otherwise HTML will linearize them.

Anyway - the data you supplied showed NO matching cases that would be printed with the code I wrote.

After I added this line into the first file: 

chr1    3205904    3207317

It correctly printed the contents expected, sot the code works as I expect.

As suggested earlier, perl debug can help find why it does not behave as you might expect it to.
