Rational Developer for System z, Version 7.6

Using the migration help

You use the migration help function on a Program or Screen to see whether there are discrepancies between the Cobol generated in VA Pac and the locally-generated code.

Before you begin
To be able to use the migration help, you must previously:
  1. In RDz, open a location (it must be represented by open location) from the Design explorer view.
  2. Right-click on a Program/Screen instance and select Migration help in the popup menu. This opens a two-page wizard:
    • On the first page, you specify the two Cobol files generated in VA Pac. Then click Finish if you want to leave the default option related to the constants and the generation date. When the wizard is opened for the first time, the default option consists in replacing the constants and date of the VA Pac generated file with those of the locally-generated file. If you want to see what the default option is or if you want to modify it, click Next to access the second page of the wizard.
    • On the second page, you indicate whether you want to keep the Pac constants and date of the VA Pac generated file, and if so, whether a warning is to be displayed on the corresponding lines. Then click Finish.
Results
The migration help function copies the two VA Pac generated Cobol files into the location and generates the local Cobol file. It compares the content of the control file with that of the locally-generated file and puts warnings wherever it finds discrepancies.

To view these warnings, you must open the generated Cobol file with the PDP LPEX editor. The warnings are displayed directly on the Cobol lines and in the Problems view. They remain as long as you do not fix them (three quick fixes are available) or generate a new code.
