Step 5: Configure VTAM

Edit online
This step is required if you plan to use the Interactive Debug Facility of HLASM Toolkit Feature to debug your batch programs interactively. A sample VTAM® definition member, ASMTAPPL.B, is supplied in the install library to help you do this. If you installed using the Interactive Interface, this member is also supplied as ASMIAPPL in ICCF library 62.
  1. Either :
    • Copy the ASMTAPPL.B member to the source sublibrary containing your VTAM definition members.
  2. or
    • Copy the HLASM Toolkit Feature minor node definitions (APPL statements) from ASMTAPPL.B into one of your existing application major node definitions.
      Note: The ASMTAPPL.B defines 20 application minor node names, ASMTL001 to ASMTL020. You can define up to 999 HLASM Toolkit Feature minor node names; the first five characters must be ASMTL and the last three characters must be consecutive 3-digit numbers, starting at 001.
  3. Add the source sublibrary member name (ASMTAPPL, or the name of the updated member) to your VTAM start options configuration file, ATCCONxx.
  4. Restart VTAM to activate the HLASM Toolkit Feature definitions.
    Until you restart VTAM, you can activate the HLASM Toolkit Feature definitions by entering the following command from your VTAM console: 
    VARY NET,ACT,ID=member-name,SCOPE=ALL
    where member-name is the source sublibrary member name (for example, ASMTAPPL).
