MESSAGELOG

Graphical display of all messages from within a macro

<UNUSED>
<UNUSED>
<ROWS>   Number of rows in window    [DEF=20]
<COLS>   Number of columns in window [DEF=132]

MESSAGELOG creates a window in which text messages are displayed.  Typically it
is used to display informational, warning, or error messages from a macro.   The
message display includes message type, date/time and message text  color-coded
by severity:  white for informational messages, yellow for warning messages, and
red for error messages.

Which severity levels are displayed is controlled by the on-off toggle buttons
"Error On", "Warning On", and "Info On" located at the bottom of the window.
These settings can be modified interactively by clicking on the buttons to
toggle them on and off. (These buttons do not control the messages being
recorded to a logfile.)

MESSAGELOG must have an /id=n switch, so that it can receive messages.

Macros send messages to MESSAGELOG, as shown in this sample macro:

  startmacro
    pipe on
      messagelog/id=msglog/msgid=main/file=temp
      res SEVERITY 2
      message send msglog ,, LOG ,SEVERITY, "THIS IS AN ERROR MESSAGE"
      res SEVERITY 1
      message send msglog ,, LOG ,SEVERITY, "THIS IS A WARNING MESSAGE"
      res SEVERITY 0
      message send msglog ,, LOG ,SEVERITY, "THIS IS AN INFO MESSAGE"
    pipe off
  endmacro

Severity levels are:  2=Error, 1=Warning, 0=Informational

The /FILE=filename is an output file in ASCII format which contains all messages
sent to MESSAGELOG. All severity levels are written to this file regardless of
the severity levels being displayed on the window. The /FILE switch is
optional.
