combine text files into one file

I need to write a shell script which combines/joins 3 text files into one file. Do i put the txt files in the same folder as my script? Here is what i have:

if [ $# -ne 3 ]
echo "$(basename $0) file1 file2 file3"
exit 1
if [ ! -f $file1 ]
echo "$file1 not a file!"
exit 2
if [ ! -f $file2 ]
echo "$file2 not a file!"
exit 3
if [ ! -f $file ]
echo "$file3 not a file!"
exit 4

cat $file1 $file2 $file3 >> $out
count=$(cat $out | wc -w)
echo "$count words written to $out"
# 2  
You don't have to put them in the same directory. Just make sure you give the full path to the files when executing your script. For example, you can enter: /tmp/filie1 /usr/var/spool/file2 /home/junk/file3
# 3  
so i have to say within my script, the path or location of file1,file2,and file3?
# 4  

If you are using linux, then you can use the 'paste' command... the syntax will be something like:

paste -s -d '\n' <file1> <file2> <file3> > ./pasted
