 The \&EXT() function can be used to obtain values for the same parameters as are retrived by some of the other (newer) helper functions  
 summarized in the table above, such as \&firstname() which is equivalent to \&EXT(`environment.firstname'),
 and \&parameter\_setting(\$name,\$partid) is equivalent to \&EXT(`resource.'.\$partid.`.'.\$name).
-In such cases the newer (specialized) functions are preferred to &EXT() on the basis of ease of use.
