I would like to go through some program source files before converting them
to ps, to check for lines longer than, for instance, 80 characters, so that
I don't get strange looking ps files.
Is this possible with emacs?

If you really mean 80chars, then C-u C-s ^.\{81\} should do the trick.
If you mean 80columns, it's trickier (unless you have no TABs or things
like that, such that it reduces to the 80chars problem).

If I can be allowed a little plug, I would suggest looking at my own
"wide-column.el" package. It doesn't do what you want, but it might
mean that you don't need to do what you want in the first place....

Doesn't 'grep' do this already?
grep '.\{80\}' ~/archive/viag.tex
Use the "-l" flag if you only want the filenames, not file contents.
Moreover, you can invoke grep from within Emacs: M-x grep

You are talking about emacs aren't you? Of course it is possible. :)
I looked at the other suggestions and found them lacking. So I wrote a little function that puts the cursor (point) on the desired column of any line longer that the desired maximum column.
Here it is:
<<find-long-line.el>>
Hope you enjoy it.
