Wang to AS/400 - Wang to MicroFocus

What we do with the Wang VS COBOL program…

  • Automatically converts Wang VS COBOL to native AS/400 COBOL.

  • All converted code maintains the original alignment of the original Wang source code.

  • All comments in the original code can be carried through to the migrated code.

  • COBOL data-names generated by the utility are extensions of existing field-names found in the program.

    What about the map definition and I/O …

  • Each Wang screen definition is converted to native AS/400 Data Display Specifications.

  • Wang COBOL names are coded into DDS field area for auto-documentation.

  • Wang FAC logic is converted to AS/400 indicator logic.

  • All features of the Wang DISPLAY and READ are supported, including NO-MOD, ON PF KEY, and enabling or disabling the ENTER KEY.

  • PF key feedback, cursor feedback and positioning are converted to retain the "look and feel" of the original transaction.

  • The original screen layouts are preserved, and the conversion is transparent to the user. No changes in input method are required.

  • The migration tool replaces all map related statements with the equivalent AS/400 statements.

    And special Wang VS COBOL functions …

  • Wang SELECT and file descriptions become AS/400 externally described files, transaction files, or printer files.

  • Alternate key files become AS/400 logical files.

  • Multiple record formats in one physical file get the required logical files.

  • On OPEN OUTPUT, if the file does not exist, code is generated to dynamically create it.

  • I/O (File name, library, volume) is redirected into native AS/400 code.

  • Code is generated to support RETURN-CODE.
