thanks to Phil and Eric

some responses and what I have done so far:

the reason for wanting an editor for these files is that Stata will not
correctly import them using -insheet- (or anything else I tried) due to
"problems" in the data (e.g., one file had 2 successive end-of-line
characters in the middle of what was supposed to be a line of data); so
I want to look at the small number of files with apparent problems to
see if I can fix them prior to importing; since I don't know what the
problem is or even where it occurs, I have been unable to figure out how
to use -filefilter-

I downloaded micvim, ultraedit (trial version) and two different emacs
versions; ultraedit did open the files but was so slow at even moving
within the file that I deleted the program; the emacs programs were a
little better but not much; micvim appears to work well, though I still
haven't figured out how to get it to show what are ordinarily "hidden"
characters (e.g., tab, eol); I need to see these to "fix" at least two
files; however, just opening the files solved one problem for me: it
told me how many lines of data there were supposed to be so I can check
the results of importing

Also, you can view just a part of the file from terminal by using the 'head' or 'tail' commands to see the start or end of the large text file very quickly (e.g.,  head -n 100 myfile.txt  to see the first 100 lines).  Finally, if you need to edit or make changes to the file before importing into Stata as a dataset, consider using -filefilter- to make changes to the file.
