Splitting fields

I have an app that is reading through a file and reformatting it.
Currently, it expects there to be 12 or more fields, and each one gets
formatted specially.

However, just recently, it was discovered that occasionally some of the
input fields can be so large that they crash into the previous field.

As an example, what normally would :
Jan 12.34 56.0 789.0 ...

shows up as
Jan 12.34 56.0-100.0 ...

Does anyone have a technique by which I could 'loop through' all the fields,
looking for this case (Each time, the field would match [0-9]+-[0-9]
+ ),
and a) split the two fields, and b) reset the record so that , for example
in the second example above, I could 'correct' the data so that it
became
Jan 12.34 56.0 -100.0 ...
before the remainder of the processing takes place.

Or am I forced to do that before awk starts reading the data?

In gawk:

$0 = gensub(/([0-9.]+)(-[0-9.]+)/,"\\1 \\2","g")

According to John DuBois <spcecdt@deeptht.armory.com>:
:In gawk:
:
:    $0 = gensub(/([0-9.]+)(-[0-9.]+)/,"\\1 \\2","g")

Awesome - thanks so much!  That's really sweet!
I hadn't thought to reassign the resulting string back to $0 to
cause the fields to be recreated!
