I'm sorry but my first post was misleading.

The string actually looks like this:

"    BeginCaption         0, 20, 66, .."
(the whitespace can be a combination of tabs and spaces)

So I actually have to cut out "Caption" word in the <<middle>> of the
string.

Brian's hint got me on the right track. The solution I finally found
was:

pane = line.sub(/\s*Begin(\w+).*/, '\1')

Unless some expert can prove a still more tight solution I believe I
have found the best way to cut out the "Caption" part of the string.

Thank you all for your help.

Best regards,
Francis
=====================================

We go back to Kero's example, for tightness :

C:\ruby\dev\buildview>irb
irb(main):001:0> line = "BeginCaption         0, 22, 66, ..."
=> "BeginCaption         0, 22, 66, ..."
irb(main):002:0> line[/Caption/] = ""
=> ""
irb(main):003:0> line
=> "Begin         0, 22, 66, ..."
irb(main):004:0>
