Abstract
Abstract A method to perform I/O (Input/Output) operations in a data processing unit running an interpretative based program in an Interpretive Machine (IM). One example on an interpretative based program running in an IM is a Java based program. An I/O class for passing data into the interpretative based program and out of a the interpretative based program is defined. An object representing an instance of this I/O class is created. The I/O class includes a first member function called an Applet function for handling I/O operations when the IM is running as an Applet coupled to a Web browser. The Applet function has its own procedures and data variables for performing I/O operations. The I/O class includes a second member function called and Application function for handling I/O operations when the IM is running as an Application not coupled to a Web browser. The Application function has its own procedures and variables for performing I/O operations. A check is made to determine whether the interpretative based program is being executed with or without a browser. When the interpretative based program is being executed with a browser, the Applet function performs I/O operations and when the interpretive based program is being executed without a browser, the Application function performs the I/O operations. In accordance with another embodiment of the present invention, a computer readable medium is disclosed corresponding to the above method.

Claims Analysis
Total Claims: 19
Claim 1
Independent Claim
220 words
A method to perform I/O (Input/Output) operations in a data processing unit comprising the steps of: executing an interpretative based program on an Interpretative Machine (IM); defining an I/O class for passing data into said program and for passing data out of said program; creating an object with a first class method based on said I/O class for said interpretative based program for execution on an IM not coupled to a Web browser and a second class method based on said I/O class for execution on an IM coupled to a Web browser; wherein said object is an instance of said I/O class with said I/O class having its own procedures and data variables for performing I/O operations; checking to determine whether said interpretative based program is being executed on an IM not coupled to a Web browser or on an IM coupled to a Web browser; if said interpretative based program is executing on an IM not coupled to a Web browser executing said first class method; wherein said first class method perform I/O operations during execution of said interpretative based program; and if said interpretative based program is executing on an IM coupled to a Web browser executing said second class method; wherein either said second class method perform I/O operations during execution of said interpretative based program.
