JOIN SEXP

 Function
  Execute the join conference command with desired sub-commands.

 Syntax
  JOIN cmds

   cmds  - A string expression with any desired sub-commands for the
           join conference command.

 Remarks
  This statement will allow you to access the join conference (the J
  command from the main menu), and any join conference sub-commands, under
  PPE control.  Note that this statement will destroy any previously
  tokenized string expression.  If you have string tokens pending at the
  time of a JOIN you should save them first and then retokenize after
  the JOIN is complete.

 Examples
  STRING yn
  INPUTYN "Join SysOp conference",yn,@X0E
  IF (yn = YESCHAR()) JOIN 4
