Hello, everyone.  I wonder if someone can explain what seems to
me an inconsistency in the command the <return> key invokes in
Berkeley Mail.
 
I'm using a PC with VT102 to Telnet into a UNIX system.If I
invoke 'mail' with messages waiting, one press of the <return>
key will, quite naturally, display Message 1.  If I delete that
message with the 'd' command (making "2" the current message) and
then press <return>, the message displayed is not Message 2, but
rather Message 3.  Why is it that if "1" is the current message,
<return> will print that message, but if any other number is the
current message, <return> will display the next message in the
queue, that is, the current message plus one?  The 'man mail'
page says 'RETURN' or "NEWLINE' works like the 'print' command,
but, as I interpret the 'print' command, <return> only works like
'p' if the current message happens to be 1.
 
Thanks for any and all help.
