Hi there ,
 
    I've just  finished  writing a listserv interface.
    It's basic purpose is to help the users .
  It provides  users with  functions such as  searching for  a
  list or a group of lists  ,  subscribing/signing  off from a
  list , getting information about a list .
    It uses file  'Listserv Lists'  from listserv , containing
  all the worldwide currently existing lists .
 
    In more details it has the following functions :
 
  *** Search for a SPECIFIC LIST ; that is, the user gives the
  name of  the list he  is interesting  in, to find  out if it
  really exists and where it is located .
 
  *** Search for a GROUP OF LISTS containing a generic string;
  that is the user gives a string ,for examble  'net', that he
  is interested in and the program searches all the entries in
  the  'Listserv  Lists'  file  to  find the  string  *net*  .
  Especially , it looks for it in the first field of each list
  entry -  which is the list name -  and in the last one - the
  description field .
 
  *** Search for all available LISTS IN A NODE  ; that is, the
  user  gives  the  node name  ,for examble XYZEARN ,  and the
  program  ,  in case that it is a valid  NJE node,  scans the
  same file  as above to find all the  lists available in that
  node ;  otherwise the user is notified for the non-existence
  of that node .
 
  *** Get information on a SPECIFIC LIST ;  the user gives the
  list  name  ,  for examble  'Ibm-nets'   ,  and the  program
  provides him with all the peered lists - if any  ;  the user
  selects one or more of them to get the  description of  that
  list(s).  If more  info are  needed  then  it  sends  a file
  containing a  'Review'  command to listserv which serves the
  above list .
 
  *** Subscribe to a list  ;  the user gives the list name and
  the program finds  all the locations of  that list  and asks
  the user where to submit his subscription .
 
  ***   Signoff from a list ; same as the subscription option .
 
    For the first  three options  ,  if  any  lists match  our
  criteria , they are displayed in a special screen which also
  provides the user  with the last three options  (  the  user
  probably  would  like  to  have information about the  lists
  found and/or to subscribe to one or more of them ) .
 
    The program runs under  VM/SP  Release  5 using RSCS V1 or
  RSCS V2 . It is written in Pascal and Rexx .
 
  ************************************************************
 
  I put the program in a package to LISTSERV AT GREARN , under
  the name :
       LISTSO PACKAGE  -  for the object code
    &  LISTSS PACKAGE  -  for the source
 
  P.S :  Be aware of the fact that the package uses file 'LISTSERV
       LISTS' from Listserv  -  about 2000 lines -  under the name
       'FILE LISTSERV' .
