Using the samples

To extract the included source code you can use the menu entry 
Services/Copy to file while RXT&T is being displayed by the view program 
and the source code is the active window. The view program then creates a 
file named TEXT.TMP in the current directory. If you selected the correct 
window to copy, the TEXT.TMP file will contain the source code that is 
displayed in RXT&T. 
After that double click on to start the OS/2 editor and load TEXT.TMP. 
Insert the necessary REXX comment marks beginning in the first column of 
the first line of the file and save it with a descriptive filename and the 
extension .CMD. (e.g., you might use a name like FILTER.CMD if you save 
the REXX code in the chapter  Writing filter programs in REXX). At that 
point, you can double click on the file to start a CMD window to test the 
REXX program. Another method is to invoke the REXX program from the OS/2 
command line by typing its name, any necessary parameters, and pressing 
the ENTER key (Double click on to start a CMD window to test the REXX 
program right now). 
You can also just double click on to start the REXX program REXXTRY.CMD to 
do some testing. Or double click on to start REXXTRY using PMREXX. (see 
also Extend the program REXXTRY)   
Note:  By using a special environment variable, IPF_KEYS (see Using IPF 
       Keys), you can have a small window containing the icons mentioned 
       above always open. This window gives you quick access to the 
       editor, command window, REXXTRY, PMREXX, and information on how to 
       use them with the sample code in RXT&T. Alternatively, you can 
       display this window by clicking on the icon 
        in the window with the source code. 
       See the section Using IPF Keys for information on automatically 
       opening the window (also called the "codemenu") whenever you view 
       source code samples in RXT&T. Also, see the section Icons Used in 
       REXX Tips & Tricks for a list of the "shortcut" icons in this
