Humm. Here is what I get when I run the program in IDL 5.5 windows:

IDL> test_xdisplayfile
1 12 12 14000 14000.0 1000
2 24 24 26000 26000.0 1000
3 36 36 38000 38000.0 1000
4 48 48 50000 50000.0 1000
5 60 60 62000 62000.0 1000
6 72 72 74000 74000.0 1000
7 84 84 86000 86000.0 1000
8 96 96 98000 98000.0 1000
9 108 108 110000 110000. 1000
10 120 120 122000 122000. 1000

Cheers,
