The command given Cat file1, file2, file3 >> file4 will fail for two reasons:
Code:
Cat: command not found
cat file1, file2, file3 
cat: file1,: No such file or directory
cat: file2,: No such file or directory

The phenomenon that you describe is due to a non-standard *nix text file, which NEEDS a terminating newline char which is obviously missing in your files. You can combine the files as desired but with additional efforts.

The Export and Echo commands won't work for the same reason as Cat above - leading upper case. Question is why there are no error messages.
Lower case should work:
Code:
echo $ var1. 
$ var1.

If you want the variable expanded, remove the space after the $ sign.

pref

environ(4)							   File Formats 							environ(4)

NAME

       environ, pref, variables - user-preference variables files for AT&T FACE

SYNOPSIS

       $HOME/pref/.environ

       $HOME/pref/.variables

       $HOME/FILECABINET/.pref

       $HOME/WASTEBASKET/.pref

DESCRIPTION

       The  .environ,  .pref,  and .variables files contain variables that indicate user preferences for a variety of operations. The .environ and
       .variables files are located under the user's $HOME/pref directory. The .pref files are found under  $HOME/FILECABINET,	$HOME/WASTEBASKET,
       and any directory where preferences were set via the organize command. Names and descriptions for each variable are presented below.  Vari-
       ables are listed one per line and are of the form variable=value.

   .environ Variables
       Variables found in .environ include:

       LOGINWIN[1-4]   Windows that are opened when FACE is initialized.

       SORTMODE        Sort mode for file folder listings. Values include the following hexadecimal digits:

		       1	Sorted alphabetically by name.

		       2	Files most recently modified first.

		       800	Sorted alphabetically by object type.

		       The values above may be listed in reverse order by ORing the following value:

		       1000	List objects in reverse order. For example, a value of 1002  will  produce  a  folder  listing	with  files  LEAST
				recently  modified  displayed first. A value of 1001 would produce a "reverse" alphabetical by name listing of the
				folder.

       DISPLAYMODE     Display mode for file folders. Values include the following hexadecimal digits:

		       0	File names only.

		       4	File names and brief description.

       PRINCMD[1-3]    Print command defined to print files.

       UMASK	       Holds default permissions with which files will be created.

   .pref Variables
       Variables found in .pref are the following:

       SORTMODE        Contains the same values as the SORTMODE variable described in .environ above.

       DISPMODE        Contains the same values as the DISPLAYMODE variable described in .environ above.
