The standard plug-in installation allows you to run all command line type Rexx programs and DrRexx type visual Rexx programs. Other visual Rexx programs require additional run-times to be installed on your machine. You can install those run-times from the Install Runtimes page.
Due to bugs in various browsers not all the example programs will run on all browsers. The browsers that can run each example program are noted in the description for that program. Mozilla in the browser list refers to Mozilla versions 1.1b or higher, or IBM Web Browser version 2 or higher.

This example queries the foreground and background colors used in the Rexx output window and returns those colors as hexadecimal values. The hexadecimal values can be used in the BGCOLOR and FGCOLOR parameters to change the colors of the output window.
After you start the program the color of the output window can be changed with the OS/2 Solid Color Palette and then queried to obtain the hexadecimal value for a specific color. The program also demonstrates how to close the browser window when the program is finished.

This program demonstrates passing values from JavaScript to Rexx,
using
user defined parameters
in the EMBED.
The HTML form has every type of input control defined in HTML. The
HTML file uses a JavaScript function to pass all the input controls
from the HTML form to the Rexx program via EMBED tag
parameters.

The program is a second version of the above program. It does the same thing, except that is uses the JavaScript command to pass values into the open HTML screen rather than modifying the HTML file before displaying it.
The Opera browser will not allow a JavaScript program in one window to set variables in a JavaScript program running in another window. Therefor this example will not run on Opera browsers.

This program demonstrates sending messages from one plug-in instance to another The program is a simple DrDialog/DrRexx program that starts a second thread and reads messages from the message pipe on that secondary thread. Each message sent from the plug-in is displayed in a list box in the application.
To run this demonstration, open this application, then open the Command Processor application and enter send a message from the command processor application.

This example shows a simple DrDialog/DrRexx program that starts a second thread and reads window position messages from the plug-in window message pipe on that secondary thread. Each message sent from the plug-in is displayed in a list box in the application.
The window message pipe is useful when the normal methods of linking an application to the plug-in do not work. For example some applications conflict with xPager when using regular linkage methods. by the application in the normal way.

Requires the VX-Rexx runtime installed on your machine. Select VX-Rexx from Step 3 of the install page. The program is the calculator sample program from the VX-Rexx distribution modified to work with the plug-in. The program displays a calculator with graphical keys. It demonstrates a graphical Rexx application running as an applet on an HTML page.

This example shows a GPF Rexx program that illustrates a Rexx application as applet integrated into the HTML page. It also shows how advanced OS/2 PM and desktop features can be integrated into plug-in Rexx program.
This example creates two containers and populates the left container with items from a data file (gpfstaff.dat). You can drag objects from one container to the other container.
This program show drag and drop capabilities on a web page. The drag and drop in this program is limited to the program itself. With some additional GPF programming the objects could be dragged to the Desktop printer or shredder.
Two versions of the GPF demo are provided below: a compressed version
and a non-compressed version. The compressed version contains the GPF
program executable, along with the data file (gpfstaff.dat) used to
populate the container. Since both files are contained in the single zip
file, only one file transfer is needed from the web server. The <EMBED>
parameter zippedFlag=1
identifies to the plug-in that the file
specified in the SRC parameter is a zipped file. The GPF Rexx application
queries the zippedFlag
parameter to determine where to get the data file.
The second version is the uncompressed version. In this version the GPF application fetches the data file (gpfstaff.dat) from the web server.

This example shows the plug-in running a Rexx program that utilizes VRexx2 functions for creating graphical windows and such. Because of the way windows are sized in VRexx2 it is impossible to run a VRexx2 application as an "applet"; instead it must run in its own window.

This example shows the plug-in running a Rexx program that utilizes the Rexx/TK library for creating windows. Because there is no facility in TK for removing the window title bar and system menu it is impossible to run a Rexx/TK application as an "applet"; instead it must run in its own window.
