This variable is designed for those calling a Java program from COBOL via the C$JAVA library routine. By default, the Java Virtual Machine (JVM) is loaded by the runtime the first time it executes a CALL C$JAVA statement. If you want to load the JVM when the runtime is started, set this configuration variable to 1. If you do not want to preload the JVM, set the variable to 0.
See C$JAVA and Calling the C$JAVA Routine for more information.
