Defining USS tables for use with the LANGTAB operand

A character-coded command that follows the USS command syntax rules (see the z/OS Communications Server: SNA Resource Definition Reference) is referred to as a USS command. A session-level USS table can be used to convert the USS command into a field-formatted SNA request. If a character-coded command violates these syntax rules, an interpret table must be used for the conversion.

The following restrictions apply when defining a USS table used for LANGTAB:

The name of the USS tables you code must match the name the user specifies on the LANGTAB operand.
The name of the USS table cannot be ISTINCNO or ISTCFCMM.
FORMAT=DYNAMIC must be coded on the USSTAB macro to use the table for LANGTAB.
If TABLE is coded on the USSTAB macro, it is ignored because the input translation table cannot be specified by the user.
USS message text must comply with the rules detailed in the z/OS Communications Server: SNA Resource Definition Reference.
