! THE SEND ROUTINE IS MADE UP OF A FORTRAN PROGRAM THAT SENDS MESSAGES TO
! OTHER TERMINALS BY TTY NUMBER.
! THE UTILITY WORKS BY CALLING A ROUTINE CALLED GET_LINE
! WHICH GETS AND PARSES THE GIVEN COMMAND LINE
! THIS PROGRAM MUST BE ABLE TO USE BROADCAST (JUMP PRIORITY)
! IN ORDER TO WORK.
! THE PROGRAM MUST BE NAMED SEND IN ORDER FOR THE PARSER TO WORK.
! IF THE PROGRAM CHANGES NAME, GET_COMMAND MUST REFLECT THIS.
! THIS PROGRAM WILL WORK IN THE CASES WHEN THE COMMAND INTERPRETOR
! DOES NOT SEND THE PROGRAM NAME ALONG.

The SEND utility enables a user to send a message to another user
who is currently logged in.

If the user ends his command line with a "+", the utility will
send the first line to the specified terminal and then request another
line of message from the user.
	
If the user ends his command line with a "*", his terminal will be
placed in dialog mode to the specified terminal.
This enables a dialog between two terminals (both terminals must be
running SEND).  Use a CTRL Z to get out of dialog mode.

The terminal ID's of current users can be found via the WHO utility.

Format:	$SEND :==$DBn:[SYSEXE]SEND.EXE !In LOGSYS.COM or LOGIN.COM
	$SEND TTnn: ... MESSAGE ...

Example: $SEND TTA3: BILL HERE.  WANT TO EAT LUNCH?
