Enable Zowe Launcher Debug Mode

Use debug mode to display additional debug messages for Zowe Launcher.

Important: We highly recommend that you enable debug mode only when you want to troubleshoot issues. Disable debug mode when you are not troubleshooting. Running Zowe Launcher in debug mode can adversely affect its performance and consume a large amount of spool space.

Follow these steps:

1. Open the PROCLIB member ZWESLSTC

2. Find STDENV DD inline statements

3. Add a new line

   ZLDEBUG=ON

   By default debug mode is disabled, so the ZLDEBUG is set to OFF. To disable debug mode remove the line or set ZLDEBUG to OFF.

4. Restart ZWESLSTC Started Task.
