NAME
message - put arguments on FMLI message line
SYNOPSIS
message [-t] [-b [num]] [-o] [-w] [string]
message [-f] [-b [num]] [-o] [-w] [string]
message [-p] [-b [num]] [-o] [-w] [string]
DESCRIPTION
The message command puts string out on the FMLI message line.
If there is no string, the stdin input to message will be
used. The output of message has a duration (length of time it
remains on the message line). The default duration is
``transient'': it or one of two other durations can be
requested with the following mutually-exclusive options:
-t explicitly defines a message to have transient
duration. Transient messages remain on the message
line only until the user presses another key or a
CHECKWORLD occurs. The descriptors itemmsg, fieldmsg,
invalidmsg, choicemsg, the default-if-not-defined
value of oninterrupt, and FMLI generated error
messages (for example, from syntax errors) also output
transient duration messages. Transient messages take
precedence over both frame messages and permanent
messages.
-f defines a message to have ``frame'' duration. Frame
messages remain on the message line as long as the
frame in which they are defined is current. The
descriptor framemsg also outputs a frame duration
message. Frame messages take precedence over
permanent messages.
-p defines a message to have ``permanent'' duration.
Permanent messages remain on the message line for the
length of the FMLI session, unless explicitly replaced
by another permanent message or temporarily superseded
by a transient message or frame message. A permanent
message is not affected by navigating away from, or by
closing, the frame which generated the permanent
message. The descriptor permanentmsg also outputs a
permanent duration message.

Messages displayed with message -p will replace (change the
value of) any message currently displayed or stored via use of
the permanentmsg descriptor. Likewise, message -f will
replace any message currently displayed or stored via use of
the framemsg descriptor. If more than one message in a frame
definition file is specified with the -p option, the last one
specified will be the permanent duration message.
The string argument should always be the last argument. Other
options available with message are the following:
-b [num]
rings the terminal bell num times, where num is an
integer from 1 to 10. The default value is 1. If the
terminal has no bell, the screen will flash num times
instead, if possible.
-o forces message to duplicate its message to stdout.
-w turns on the working indicator.
EXAMPLES
When a value entered in a field is invalid, ring the bell 3
times and then display Invalid Entry: Try again! on the
message line:
invalidmsg=`message -b 3 "Invalid Entry: Try again!"`
Display a message that tells the user what is being done:
done=`message EDITOR has been set in your environment` close
Display a message on the message line and stdout for each
field in a form (a pseudo-"field duration" message).
fieldmsg="`message -o -f "Enter a filename."`"
Display a blank transient message (effect is to ``remove'' a
permanent or frame duration message).
done=`message ""` nop
NOTICES
If message is coded more than once on a single line, it may
appear that only the right-most instance is interpreted and
displayed. Use sleep(1) between uses of message in this case,

to display multiple messages.
message -f should not be used in a stand-alone backquoted
expression or with the init descriptor because the frame is
not yet current when these are evaluated.
In cases where `message -f "string"` is part of a stand-alone
backquoted expression, the context for evaluation of the
expression is the previously current frame. The previously
current frame can be the frame that issued the open command
for the frame containing the backquoted expression, or it can
be a frame given as an argument when fmli was invoked. That
is, the previously current frame is the one whose frame
message will be modified.
Permanent duration messages are displayed when the user
navigates to the command line.
