ΓòÉΓòÉΓòÉ 2. Introduction ΓòÉΓòÉΓòÉ

The myNstall ([maj:]Nstall) is the universal small installation PM-program.

It uses control words to arrange the installation process and gives you the
interface to your own Rexx routines, so that you can design the installation
process with more flexibility as you are now able to. Of course you can omit
all these controls and work with the default values as delivered.

If you want to work without the control words, you can use this routine as is.
It copies almost all files (with exception of hidden and system files) from the
home directory into the selected destination directory.

ΓòÉΓòÉΓòÉ 2.1. myNstall revision history ΓòÉΓòÉΓòÉ

These are the new features that were added for the version 1.01 Beta of
myNstall.

Following keywords for the control file INSTALL.DAT were added:

   1. WPS_ONLY_IF_EXIST= to hide/show the check box "Create WPS object only".
   2. WELCOME_BUTTON=OKCANCEL | OK to show in the Welcome message of your
      installation the buttons OK and Cancel or OK only.
   3. WELCOME_TITLE= to set the Title for this message.
   4. WELCOME= to set the message text. You can use this keyword multiple
      times.
   5. START_REXX_BY_OPEN_WINDOW= to start your own Rexx routine at the start of
      the installation process (Exit 1).
   6. START_REXX_BY_START_INSTALL= to call your own Rexx routine after you
      pressed the Install-Button but before the installation has started (Exit
      2).
   7. START_REXX_BY_SUCCESSFUL= to start your own Rexx routine after the
      successful installation (Exit 3).
   8. START_REXX_IF_FAILURE= to start your own Rexx routine if the installation
      has failed (Exit 4).
   9. START_REXX_BY_CLOSE_WINDOW= to start your own Rexx routine before you
      exit the installation process (Exit 5).
  10. DELETE_FILE= to delete a file from the destination directory before you
      start the installation process. You can use this keyword multiple times.
      It is useful for the update installation.
  11. REMOVE_DIR= to delete a subdirectory from the destination directory
      before you start the installation process. You can use this keyword
      multiple times. It is useful for the update installation.

 These are the new features that were added for the version 1.02 Beta of
 myNstall.

   1. DELETE_FILE_AFTER_INSTALLATION= to delete a file from the destination
      directory after successfully installing your product.
   2. REMOVE_DIR_AFTER_INSTALLATION= to delete a subdirectory from the
      destination directory  after successful installation.


ΓòÉΓòÉΓòÉ 3. System requirements ΓòÉΓòÉΓòÉ

myNstall requires approximately 200 kB (additional INSTALL.DAT) of disk space.
To use myNstall to install products, the following must be on the computer:

     OS/2 version 2.x or higher,
     Rexx support.


ΓòÉΓòÉΓòÉ 4. How to install? ΓòÉΓòÉΓòÉ

To install a product:

     Use the program INSTALL.EXE to start installation - an installation
      window will be displayed.
     Select the drive letter in the Box named Drive.
     Select the directory in the Box named Directory:
           Single click with the mouse button 1 selects the directory,
           Double click with the mouse button 1 opens the subdirectory list.
     The path to the last selected directory is showing in the entry field
      named Path.
     If you wish to install the product into a new directory, you should write
      its name into the entry field named Path.
     Select the push button Install to start the installation.
     If the destination directory not yet exists, you will be prompted for
      confirmation.
     Select Yes to install or No to cancel the installation.


ΓòÉΓòÉΓòÉ 5. How does the myNstaller work? ΓòÉΓòÉΓòÉ

To use the myNstall copy following files into your products source
(installation) directory:

     INSTALL.EXE
     INSTALL.HLP
     [INSTALL.DAT]

 INSTALL.DAT is the control file with the keywords to control your installation
 process. You don't need this file, if you don't want to use its features.

 The myNstall unpacks almost all files (with exception of files with attributes
 H (hidden) and S (system) from the home (source) directory into the current
 destination directory.

 See OS/2 UNPACK command for more info.

 Note:  If the current destination directory does not exist, it will be
 created. You will be prompted for the confirmation.

 The description of the WPS objects is situated in the file INSTALL.DAT. The
 description records must be enclosed in parenthesis ( ). If you want to create
 a folder for other objects, it must be placed at the beginning of the listing.
 For the syntax see the parameter list of the REXX function SysCreateObject.

 Note:  You can only use one (1) line for one (1) description record. i.e.:

          /*------(start WPS objects)-----*/
          ("WPFolder", title, location, associations, "r")
          ("WPProgram", title, location, associations, "r")
             other descriptions record
             other descriptions record
          /*------(end WPS objects)-----*/

 See chapter Control words (keywords) in this file for more information.

   1. DESTINATION=destination_directory_path
   2. WPS_ONLY_IF_EXIST=file_name

   4. WELCOME_TITLE=message_title
   5. WELCOME_BUTTON={OK | OKCANCEL}
   6. START_REXX_BY_OPEN_WINDOW=rexxcall
   7. START_REXX_BY_START_INSTALL=rexxcall
   8. START_REXX_BY_SUCCESSFUL=rexxcall
   9. START_REXX_BY_FAILURE=rexxcall
  10. START_REXX_BY_CLOSE_WINDOW=rexxcall
  11. DEST_PATH (used by SysCreateObject and your own Rexx)

  13. DELETE_FILE
  14. REMOVE_DIR
  15. DELETE_FILE_AFTER_INSTALLATION
  16. REMOVE_DIR_AFTER_INSTALLATION

 See chapter Control words (keywords) for more details.


ΓòÉΓòÉΓòÉ 7. Control words (keywords) ΓòÉΓòÉΓòÉ

Note:  You can write the keywords into the file INSTALL.DAT in any order!

In the follwing chapters are described keywords which you can use in the
control file INSTALL.DAT.

Remember:  you can omit all these controls and work with default values only.


ΓòÉΓòÉΓòÉ 7.1. Destination path ΓòÉΓòÉΓòÉ

DESTINATION=destination_directory_path

This keyword identifies the record from file INSTALL.DAT which sets the name of
the standard destination directory.

If you omit this name, the root directory of the drive C: will be used.

You should omit the leading and ending backslashes and the drive character.

Default value:   root directory of the drive C: (drive C: is always the default
drive. Everybody has drive C: - don't they?).

Example:  DESTINATION=TOOLS\INSTALL


ΓòÉΓòÉΓòÉ 7.2. Create WPS object only ΓòÉΓòÉΓòÉ

WPS_ONLY_IF_EXIST=file_name

The Installer is able to recreate the damaged WPS-Objects for your
installation. It does this if the Check Box Create WPS objects only is
selected. But it is not necessary to show this box if the user is doing his
first installation. You can hide this Check Box for the installation window if
you
