Abstract

A method of distributing mainframe software and data using PC-based data media is disclosed, comprising a mainframe program for converting a mainframe sequential dataset or all or part of a mainframe library of texts or load modules to a sequential dataset of fixed length records and for reverting these converted records to its original form in the same or another mainframe data center, and procedures for downloading the converted mainframe data to a PC and uploading the PC file to a mainframe. The converted mainframe data downloaded to a PC can be delivered to another mainframe data center using floppy diskettes, recordable CD-ROM, Internet Website, TCP/IP FTP, or email attachment, as an alternative to magnetic tapes. The PC hard disk is used as a backup storage of the mainframe libraries, and a mainframe text library downloaded to a PC can be edited on a local or remote stand-alone PC.

Claims

1. An apparatus implemented with processor and memory for distributing computer data, comprising:

sender having program logic for converting sender data to sender terminal file in sender terminal; and

receiver having program logic for reverting receiver terminal file in receiver terminal into receiver data without losing integrity of said sender data in said converting or said reverting;

wherein each unit of said sender data is concatenated into said sender terminal file in said converting;

wherein each data unit of said receiver terminal file is separated in said reverting; and

wherein said sender terminal file and said receiver terminal file are same terminal file or, for also sending and receiving said sender and receiver terminal file, different terminal files.

2. The apparatus according to claim 1, wherein said sender computer and said receiver computer are one of same or different computers.

3. The apparatus according to claim 1, wherein at least one of said sender terminal file or said receiver terminal file is part or whole of said sender data.

4. The apparatus according to claim 1, wherein said sender data and said receiver data are one of the same or different from each other.

5. The apparatus according to claim 1, wherein said receiver data has same form as said sender data.

6. An apparatus implemented with processor and memory for distributing device data, comprising:

sender having program logic for converting sender data to sender terminal file in sender terminal; and

receiver having program logic for reverting receiver terminal file in receiver terminal into receiver data without losing integrity of said sender data in said converting or said reverting;

wherein each unit of said sender data is concatenated into said sender terminal file in said converting;

wherein each data unit of said receiver terminal file is separated in said reverting; and

wherein said sender terminal file and said receiver terminal file are same terminal file or, for also sending and receiving said sender and receiver terminal file, different terminal files.

7. The apparatus according to claim 6, wherein said sender and said receiver are one of same or different devices.

8. The apparatus according to claim 6, wherein at least one of said sender terminal file or said receiver terminal file is part or whole of said sender data.

9. The apparatus according to claim 6, wherein said sender data and said receiver data are one of the same or different from each other.

10. The apparatus according to claim 6, wherein said receiver data has same form as said sender data.

11. An apparatus implemented with processor and memory for distributing computer data, comprising:

sender having program logic for converting sender data to sender terminal file in sender terminal; and

receiver having program logic for reverting receiver terminal file in receiver terminal into receiver data of original form without losing data integrity in said converting or said reverting;

wherein each unit of said sender data is concatenated into said sender terminal file in said converting;

wherein each data unit of said receiver terminal file is separated in said reverting; and

wherein said sender terminal file and said receiver terminal file are same terminal file or, for also sending and receiving said sender and receiver terminal file, different terminal files.

12. The apparatus according to claim 11, wherein said sender and said receiver are one of same or different computers.

13. The apparatus according to claim 11, wherein said sender data and said receiver data are one of the same or different from each other.

14. The apparatus according to claim 11, wherein at least one of said sender terminal file or said receiver terminal file is part or whole of said sender data.
