load signed data joins problem

I found a problem loading data: I have a file of signed numbers like:

-1.370674456E+02-1.662854139E+02 0.000000000E+00 0.000000000E+00 0.000000000E+00
6.964865599E+10 8.394798002E-11 4.348192658E+03 9.455873862E+02 3.292484968E-09

The problem is that the signed numbers join so I always find an error if I try to load this data.

Any idea of how to bypass it?

Thank you!
