.SH DESCRIPTION
(it is the default
.IR showproc ).
.PP
-As with
-.BR more ,
-each of the messages specified as arguments (or
-the standard input) will be output. If more than one message file is
-specified, the user will be prompted prior to each one, and a <RETURN>
-or <EOT> will begin the output, with <RETURN> clearing the screen (if
-appropriate), and <EOT> (usually CTRL\-D) suppressing the screen clear.
-An <INTERRUPT> (usually CTRL\-C) will abort the current message output,
-prompting for the next message (if there is one), and a <QUIT> (usually
-CTRL-\\) will terminate the program (without core dump).
-.PP
-The
-.B \-bell
-option tells
-.B mhl
-to ring the terminal's bell at the
-end of each page, while the
-.B \-clear
-option tells
-.B mhl
-to clear the
-screen at the end of each page (or output a formfeed after each message).
-Both of these switches (and their inverse counterparts) take effect only
-if the profile entry
-.I moreproc
-is defined but empty, and
-.B mhl
-is outputting to a terminal. If the
-.I moreproc
-entry is defined and
-non-empty, and
-.B mhl
-is outputting to a terminal, then
-.B mhl
-will
-cause the
-.I moreproc
-to be placed between the terminal and
-.B mhl
-and the switches are ignored. Furthermore, if the
-.B \-clear
-switch is
-used and \fImhl's\fR output is directed to a terminal, then
-.B mhl
-will consult the
-.B $TERM
-and
-.B $TERMCAP
-environment variables
-to determine the user's terminal type in order to find out how to clear
-the screen. If the
-.B \-clear
-switch is used and
-.BR mhl 's
-output is
-not directed to a terminal (e.g., a pipe or a file), then
-.B mhl
-will
-send a formfeed after each message.
-.PP
-To override the default
-.I moreproc
-and the profile entry, use the
-.B \-moreproc
-.I program
-switch. Note that
-.B mhl
-will never start a
-.I moreproc
-if invoked on a hardcopy terminal.
-.PP
The
-.B \-length
-.I length
-and
.B \-width
.I width
-switches set the screen
-length and width, respectively. These default to the values indicated by

switch.
-.PP
-Finally, the
-.B \-folder
-.I +folder
-switch sets the
-.B nmh
-folder name,
-which is used for the \*(lqmessagename:\*(rq field described below. The
-environment variable
-.B $mhfolder
-is consulted for the default value,
-which
-.BR show ,
-.BR next ,
-and

-initialize appropriately.
+Note: In contrast to any other
+.B mmh
+tool, the
+.B \-form
+switch does only take file names, but no format strings with a prepended
+equal sign `='.
.PP
.B Mhl
operates in two phases: 1) read and parse the format file, and
is walked for each message, outputting message information under the
format constraints from the format file.
.PP
-The format file can contain information controlling screen clearing,
+The format file can contain information controlling
screen size, wrap\-around control, transparent text, component ordering,
and component formatting. Also, a list of components to ignore may be
specified, and a couple of \*(lqspecial\*(rq components are defined
For example, the line:
.PP
.RS 5
-width=80,length=40,clearscreen,overflowtext="***",overflowoffset=5
+width=80,overflowtext="***",overflowoffset=5
.RE
.PP
defines the screen size to be 80 columns by 40 rows, specifies that the
-screen should be cleared prior to each page, that the overflow indentation
+overflow indentation
is 5, and that overflow text should be flagged with \*(lq***\*(rq.
.PP
Following are all of the current variables and their arguments. If they
affect is global. Since the whole format is parsed before any output
processing, the last global switch setting for a variable applies to
the whole message if that variable is used in a global context (i.e.,
-bell, clearscreen, width, length).

.SH BUGS
-There should be some way to pass `bell' and `clear' information to the
-front\-end.
+In contrast to any other
+.B mmh
+tool, the

The \*(lqnonewline\*(rq option interacts badly with \*(lqcompress\*(rq
and \*(lqsplit\*(rq.
