PMVIEW

Purpose: A file browsing utility for the OS/2 Presentation Manager.   PMVIEW
         displays files either in ASCII or in hex, and additionally permits
         searching by phrase or jumping directly to a specified point in a
         file.

Format: PMVIEW [filename] [/i]

Remarks: PMVIEW can be invoked either from an OS/2 window or from the
         full-screen command line.  If no filename is entered initially,
         a dialog box is opened listing the available drives and files from
         which a file may be selected.   PMVIEW can also be made a part of
         the Program Manager group, in which case it can be selected from a
         menu at startup.  Adding the optional /i switch, either at the
         command line or as a parameter of the Start Programs menu, will
         load PMVIEW with a specified filename and immediately shrink it
         to an icon, making it instantly available.  The selected filename
         is shown in the title bar of the display window and as the title
         of an icon when the window is minimized.

        Search menu options for PMVIEW permit entering either a phrase or an
        offset to which the utility will jump.  Configuration options permit
        customizing the screen color, display font size, display format,
        tab stop setting, and whether or not the scroll bars should be shown.
        These settings become program defaults, but may be changed at any time.

Note: The PMVIEW.HLP file must reside in one of the following directories:
      (1) A directory specified in the HELP environment variable;
      (2) The working directory specified in the Program Properties of
          the PMVIEW menu entry when it is invoked from a PM program group; or
      (3) The current directory when PMVIEW is invoked from a command line.

Note: This version of PMVIEW requires OS/2 1.3 or later.  SYSOPS should retain
      PMVIEW4A on BBSs for those people running OS/2 1.2.

I am grateful to Tony Nadalin, author of TRASHCAN and SYSOP of the BlueEdge
BBS [phone], who for good reason would not tell me specifically the File
Manager drag and drop protocol, but who did give me some priceless hints.

If you have comments, questions, problems, etc., I can be reached on
Prodigy at SBTX21A or the HAL-PC Telecom I in Houston at [phone].
