The package property of the asynchLink element in a linkage options part is valid only for Java™ output and specifies the name of the package that contains the program being started. The default is the package of the originating program.
The package name that is used in generated Java programs is the package name of the EGL program, but in lower case; and when EGL generates output from the asynchLink element, the value of package is changed (if necessary) to lower case.
