Description
This instruction loads a DLL or a Java class into memory, in situations where you need to call one of its functions several times.
The name of the DLL or class can be an alphanumeric constant, the guide word for a Visual Adelia program or a variable preceded by the character "&".
This instruction prepares the execution of the CALL and CALL_DLL instructions.
To check whether the operation has been performed successfully, you can test the *RETURN_CODE reserved word.
Note: In the case of a client part of a WADELIA program, PgmName can only be the name of a VADELIA batch program (generated in Java client).
