NAME

       L-dialcodes - UUCP phone number index file

DESCRIPTION

       The L-dialcodes file defines the mapping of strings from the phone number field of L.sys(5) to actual phone numbers.

       Each line in L-dialcodes has the form:

	    alpha_string  phone_number

       The two items can be separated by any number of blanks or tabs. Lines beginning with a `#' character are comments.

       A  phone  number  in  L.sys  can  be  preceded  by  an  arbitrary  alphabetic  character  string; the string is matched against the list of
       alpha_strings in L-dialcodes.  If a match is found, phone_number is substituted for it. If no match is found, the string is discarded.

       L-dialcodes is commonly used either of two ways:

       (1) The alphabetic strings are used as prefixes to denote area codes, zones, and other commonly used sequences. For example, if L-dialcodes
	   included the following lines:

	    chi  1312
	    mv	 1415

       In L.sys you could enter:

	    chivax Any ACU 1200 chi5551234  ogin:--ogin: nuucp
	    mvpyr  Any ACU 1200 mv5556001   ogin:--ogin: Uuucp

       instead of

	    chivax Any ACU 1200 13125551234  ogin:--ogin: nuucp
	    mvpyr  Any ACU 1200 14155556001  ogin:--ogin: Uuucp

       (2) All phone numbers are placed in L-dialcodes, one for each remote site.  L.sys then refers to these by name. For example, if L-dialcodes
	   contains the following lines:

	    chivax    13125551234
	    mvpyr     14155556601

       then L.sys could have:

	    chivax Any ACU 1200 chivax	ogin:--ogin: nuucp
	    mvpyr  Any ACU 1200 mvpyr	ogin:--ogin: Uuucp

       This scheme allows a site administrator to give users read access to the table of phone numbers, while still protecting the  login/password
       sequences in L.sys.
