You can set the environment variable IPF_KEYS to make RXT&T display additional information that is not part of the regular display. Some of this additional information is in German, for German readers. (If you don't know German, you won't need this information.). There are other uses for IPF_KEYS, however, that anyone can use to make their use of RXT&T easier and more helpful.
To enable the additional information to be displayed, add the appropriate key(s) (see table below) to the line SET IPF_KEYS= in your CONFIG.SYS file, then reboot the computer. For temporary changes, you can change the environment variable in a single windowed or fullscreen OS/2 session. Just type the SET command with the desired key(s) and press ENTER. Then start the VIEW program (e.g., view rxtt34.inf) from within that same OS/2 session.
Note: Use the plus sign rather than a semicolon to separate the keys in the IPF_KEYS variable.
Example
SET IPF_KEYS=SCBS+RXTT_German+RXTT_MENU
This command will enable single byte character set, special notes in German language, and codemenu
SET IPF_KEYS=RXTT_MENU
This command will cause the codemenu to be displayed automatically whenever you view source code samples in RXT&T.
