Pass parameters to a Java program by specifying the parameters to be passed on the function definition. Specify only string parameters that are input-only (IN), or input or output (INOUT).
Example: The IN parameter p1 is to be passed on the function call
%function(DTW_JAVAPPS) jv1(IN p1) { %}
The Java Application language environment does not support Java programs that update variables because it cannot pass the updated values back to the macro.
