Actually I am reading an output file of a program that I do not have.

I am using R 0.64.2 under Windows 95. I soon found out that read.fwf()
requires Perl, which I did not have installed. So I downloaded ActivePerl
from http://www.activestate.com/ActivePerl/ and installed it, as well as 
DCOM for Windows 95 (required for Windows 95 machines only) - downloadable
from http://www.microsoft.com/com/dcom/dcom95/dcom1_3.asp. 

The install was straightforward (I put DCOM on first, which seemed
logical). However I still have trouble with read.fwf(). At first I thought
that it was due to spaces in my directory names, but it persisted after I
fixed this up. My complete session follows:
