Creating variables for parameters

Before passing a parameter, you must create a variable of the correct Java data type. If you want to pass the ABL Unknown value (?) (null in Java) for intrinsic types, you must use the corresponding object. The Progress to Java mappings are the same as the ones defined for passing parameters to Open Client proxy methods. For more information on the supported mappings between ABL and Java data types, see Passing Parameters.
