Abstract

An open network system for supporting input/output (I/0) operations for non-standard I/O devices are disclosed. The system includes a server coupled to a plurality of I/O devices through an open network and an extended open system protocol that supports communication with devices that are not personal computers (PCs). These devices include magnetic stripe readers, check readers, smart card readers, credit card terminals, screen phone terminals, PIN pads, printers, and the like. The extended open network protocol includes tags which identify device and input operations and attributes which identify the location, data exchange method, and data variable names for the retrieval, acquisition, and submission of data between the server and I/O devices. Preferably, the open network protocol is implemented in a Hyper Text Transport Protocol (HTTP). Preferably, the system includes a common gateway interface (CGI) at the server which converts protocol statements communicated between the server and I/O devices to application language statements for providing data to an application program coupled to the server. Most preferably, the application statements and protocol statements are constructed in integrated statements with an editor. The editor ensures that data identifiers in the application and protocol statements are compatible. The integrated statements are then parsed by the editor to segregate the protocol statements from the application statements. The protocol statements are downloaded in a file to a client program at an I/O device for processing. The application statements are stored in a file for use by the application. In this manner, generation of the files for client and application processing are automatically done without the user ensuring the correlation of the data fields in the two files.

Claims

1. An editor for developing statements to support input/output (I/O) operation on an open network comprising:

an integrated statement editor for verifying syntax of integrated statements comprised of open network protocol statements and application statements so that variable names in said protocol statements correspond with data fields in said application statements; and

a segregator for segregating said protocol statements from said application statements; and

a downloader for downloading said segregated protocol statements to an I/O device and for storing said segregated application statements for use by a common gateway interface.

2. The editor of claim 1 wherein said open network protocol statements are implemented in Hyper Text Transport Protocol;

and

said application statements are database statements.

3. The editor of claim 2 wherein said database statements are Structured Query Language statements.

4. The editor of claim 2 wherein said integrated statements include source code statements for a first processor and a second processor and said source code statements for said first and second processors are segregated and said editor further comprises:

a compiler for compiling executable code from said segregated source code statements so that executable code for both first and second processor may be generated from said integrated statements.

5. The editor of claim 4 wherein said source code statements for said first and second processors are for different languages and said editor includes a compiler for each language.

6. An editor for developing statements to support input/output (I/O) operation on an open network comprising:

an integrated statement editor for verifying syntax of integrated statements, said integrated statements being comprised of extended open network protocol statements implemented in Hyper-Text Transport Protocol and database statements so that variable names in said protocol statements correspond with data fields in said database statements;

a segregator for segregating said protocol statements in said verified integrated statements from said database statements in said verified integrated statements; and

a downloader for downloading said segregated protocol statements to an I/O device and for storing said segregated application statements for use by a common gateway interface.

7. The editor of claim 6 wherein said database statements are Structured Query Language statements.

8. The editor of claim 6 wherein said integrated statements include source code statements for a first processor and a second processor and said source code statements for said first and second processors are segregated from said verified integrated statements and said editor further comprises:

a compiler for compiling executable code from said segregated source code statements so that executable code for both first and second processor may be generated from said integrated statements.

9. The editor of claim 8 wherein said source code statements for said first and second processors are for different computer languages and said editor includes a compiler for each computer language.

10. An editor for developing statements to support input/output (I/O) operation on an open network comprising:

an integrated statement editor for verifying syntax of integrated statements, said integrated statements being comprised of source code statements for a first processor and source code statements for a second processor;

a segregator for segregating said source code statements for said first processor in said verified integrated statements from said source code statements for said second processor in said verified integrated statements; and

a compiler for compiling executable code from said segregated source code statements for said first and said second processors to generate executable code for said first and said second processors.

11. The editor of claim 10 further comprising:

a downloader for downloading executable code for said first processor to said first processor for execution and for downloading executable code for said second processor to said second processor for execution.

12. The editor of claim 10 wherein said source code statements for said first and second processors are for different computer languages and said editor includes a compiler for each computer language.
