ReadList problems in NEXTStep, version 2.2 for NEXT

Hi Mathgroup

I came across a strange problem regarding ReadList[]. I used it
extensively to import data files consisting of three columns of numbers
sepearated by a couple of spaces and after the third column another couple
of spaces appear before the end of line marker. I used those to import
data in a Solaris version of Mathematica (2.2) and Windows 3.1 (2.2.4) and
everything worked fine. I actually used "ReadList["filename", Numbers,
RecordLists -> True]" to get a nested list.

When I now do the SAME using a NEXT CUBE (version 2.2 as well) I get an
error message stating something like. ....syntax error reading in a real
number....

If I remove the trailing spaces between the third column and the end of
line marker everything is read in fine. But that is really cumbersome to
remove the trailing spaces only for that purpose.

Is there something different in the NEXT version of Mathematica which can
cause that problem in comparison to the Solaris and Windows 3.1 version

I made sure that the files were copied from the diskette which is DOS to
the CUBE using "cp" to convert the differnet end of line markers in those
two OS's. The data originally were created on an VMS system then copied to
the Solaris system and used there. From there I copied the data on a DOS
system and used them in Windows 3.1, and those DOS diskettes were used to
copy the data to the CUBE.


Can you help me with that?

Thanks a lot.
