Subject: Using Sub

Possibly overkill, I use a Windows batch file that calls a perl script. 
Both the bat and pl files need to be in the executable path. Open a 
command prompt, type `pwd ' and then drag the file or folder from the 
Windows Explorer to the cmd. The script will return the file with 
backslashes converted to forward slashes. Then I copy and paste from the 
cmd window into my R script.

c:\>more c:\bin\batch\pwd.BAT
@echo off
c:\bin\batch\pwd.pl %1

c:\>more c:\bin\batch\pwd.pl
#! /usr/bin/perl -w
# prints pwd with forward slashes for R

use File::Basename;

#print $#ARGV;

if ($#ARGV == -1) {
   $pwd = `cd`;
   chomp $pwd;
}
else {
   $pwd = $ARGV[0];
}
$pwd =~ s|\\|\/|g;
print "$pwd";

-P.
