@ALIAS

@ALIAS[name]:  Returns the contents of the specified alias as a string, or 
a null string if the alias doesn't exist.  When manipulating strings 
returned by @ALIAS you may need to disable certain special characters with 
the SETDOS /X command. Otherwise, command separators, redirection 
characters, and other similar "punctuation" in the alias may be 
interpreted as part of the current command, rather than part of a simple 
text string.
