═══ 1. About MMBrowse ═══

The MMBrowse application is a Presentation Manager application which 
demonstrates the use of the Multimedia I/O subsystem (MMIO). For more detail 
information about MMIO, please consult IBM Multimedia Presentation Manager/2 
Programming Reference. 


═══ 2. Get FOURCC ═══

Every installed MMIO I/O Procedure must have a four character code (FOURCC) 
associated with it. It must be at most four characters long. For example, the 
OS/2 1.3 Bitmap IO Proc's FOURCC is OS13. If you are unsure of what the FOURCC 
should be, please contact the author of the IO Proc you are trying to 
install/remove. 


═══ 3. Open an image file ═══

Use this choice to open an image file for viewing. 


═══ 4. Save an image file ═══

Use this choice to save an image file. The file format of the image depends on 
the image file extension, and the default one is OS/2 2.0 bitmap. 


═══ 5. Install an I/O procedure ═══

Use this choice to install a multimedia I/O procedure. For more detail 
information about MMIO, please consult IBM Multimedia Presentation Manager/2 
Programming Reference. The default file extension for IOProc is DLL, and this 
sample program requires entry point to an installed IOPROC to be 
"IOProc_Entry". 


═══ 6. Remove Permanent I/O Procedure(s) ═══

Click on any permanently installed I/O procedure(s) you wish to remove from the 
INI file. After you're done, press OK to remove. You must exit the MMBrowse 
application to have the removal of I/O procedures take effect. Since this 
sample program requires an entry point to an installed IOPROC to be 
"IOProc_Entry", the listed installed I/O procedures that can be removed are 
those that can be reinstalled. 


═══ 7. Query installed I/O Procedures ═══

listing of installed I/O procedures for the users to select. Click on any

General help provides general information about the MMBrowse application. The 
MMBROWSE program demonstrates the Multimedia  I/O concept by serving as a 
utility program for viewing and saving an image file. The program can also be 
used to install or remove temporary or permanent I/O procedures. Although this 
program needs an entry point to an installed IOPROC to be "IOProc_Entry", new 
I/O procedures can be added by using the techniques of this program.
