Window services allow HLL programs to:
Window services enable your program to access data objects without your program performing any input or output (I/O) operations. All your program needs to do is issue a CALL to the appropriate service program. The service program performs any I/O operations that are required to make the data object available to your program. When you want to update or save a data object, window services again perform any required I/O operations. |
