Creating a Map for WRITE and Copying Field Definitions

In this session, you will create a map by copying the field definitions from a DDM (data definition module). In addition, you will change the map setting so that you can use the WRITE USING MAP statement.

Start of instruction setTo create a map from DDM fields

  1. At the program editor's command prompt, enter the following:

    EDIT MAP

    The Edit Map menu appears.

  2. Execute the Initialize new Map function to create a map with the name MAP002.

    The Define Map Settings For MAP screen appears.

  3. Change Page Size to 60. Mark WRITE Statement by typing in an X in the input field next to it. Unmark INPUT Statement by removing the X next to it with SPACEBAR.

  4. Press ENTER.

    The WRITE Statement option is marked, which means that this map can only be invoked from a program with a WRITE USING MAP statement.

  5. Press ENTER twice.

    The map editing screen appears.

  6. Next to the Ob input fields at the top of the screen, enter the following:

    V EMPLOYEES
  7. Press ENTER.

    The fields definitions of the DDM EMPLOYEES are listed:
