Use VTAM® macroinstructions to create, replace, or modify VTAM’s interpret, logon mode, Class of Service, or USS tables. You can also use macroinstructions to install the associated LU, model name, or message-flooding prevention tables.

Procedure

To create, replace, or modify VTAM’s interpret, logon mode, Class of Service, or USS tables, follow these steps:

  1. Code the appropriate VTAM macroinstructions.
  2. Assemble the group of macroinstructions.
  3. Link-edit the table as a nonexecutable module into a library associated with the VTAMLIB DD statement.

Installing tables

Procedure

No assembly or link-edit is required to install the associated LU, model name, or message-flooding prevention tables. The groups of macroinstructions are stored in source-language form. To install these tables, follow these steps:

  1. Code the appropriate VTAM macroinstructions.
  2. Store the group of macroinstructions as a member in SYS1.VTAMLST. The member name is used as the name of the table.
