Topic:
Selecting "thru" buttons in Load 2D locations displays the wrong columns.

Description:
I have a navigation file that was output from Excel as tab delimited. In 
the viewer it looks ok, but when I drag a column and click on the "thru"
button it gives me columns with different numbers.

Solution:
Those tabs are causing the problem. The viewer interprets the tab and spaces
accordingly but the "thru" button looks at the actual column. To see what the
"thru" button sees, type cat -tev filename on the UNIX level.

This is the file as seen through the viewer.

naws_92_03       985.00 35454145N       117451949W      2072576 823146  2222
naws_92_03       985.50 35454087N       117451879W      2072634 823088  2222   

This is the file as seen by thru buttons and cat -tev command.

naws_92_03^I 985.00 35454145N^I117451949W^I2072576^I823146^I2222^IXXX$
naws_92_03^I 985.50 35454087N^I117451879W^I2072634^I823088^I2222^IXXX$


Having said this, if you just use the thru buttons values, the navigation
file will load correctly. There is an inconsistancy between what is seen
in the viewer and what is actually out there because the ^I (tabs) are
interpreted rather that literally being displayed.

Or, you can edit the ASCII file and take out the tabs by the command in vi mode:
:%s/control-vcontrol-i/    /g
      ^^^      ^^^
:%s/Hold control key and select v, then hold control key and select i/input spaces/g
