Resolution:
Correct the code; then recompile.
Example:
In the following example, the main static method uses a single parameter that is a string array; therefore, the ILMAIN directive is ignored when compiling for JVM.
$set ilmain(Hello) class-id Err1848. method-id Hello static. display "In Hello method" end method. method-id main static (args as string occurs any). display "In main method" end method. end class.
