# //     Script file used to change the JVM used to run the EnableJvm.class.
# //     Either because the -runAsTargetJvm switch was passed, or if the enableJvm 
# //     script is being called in a post-IBM i 6.1 release and the controlling profile  
# //     is configured to use the Classic jvm which is no longer supported.
