OW07504: USSMSG1: INVALID COMMAND SYNTAX ISSUED FROM A USS LOGON COMMAND.

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• A Uss logon attempt received USSMSG: luname INVALID COMMAND
  SYNTAX. Customer was using an INTERPRET table to pass Vtam
  the DLU's network name. The DLU's name in the INIT SELF was
  garbaged(X'F3080000 0000E600'), which caused the USSMSG1 to
  be sent to the terminal. The INTERPRET table assembled and
  linkeditted sucessfully.
  

Local fix

• Make sure all macros are present and coded in their proper
  order.

  ****************************************************************
  USSMSG1 is received for a USS logon. An INTERPRET table
  was being used and the logon sequence matched the SEQNCE field
  of the INTERPRET table. The resource name that was returned by
  INTERPRET (ISTCPCIT) was not valid. The error occurred
  because the INTERPRET table was improperly constructed (it did
  not contain the "end of table" indicator). The end of an
  INTERPRET table is indicated by a byte = x'80'. This is
  placed at the end of the INTERPRET table by the ENDINTAB macro.
  The INTERPRET table had been coded so that the Assembler
  "END" statement was before the "ENDINTAB" macro. Once the
  Assembler encountered the "END" statement, no other statements
  were processed (the ENDINTAB macro, while present in the
  source statements, was not 'seen' by the Assembler). The table
  assembled without error, however, the table was not
  correctly constructed for use by VTAM. When used, VTAM 'ran off
  the end' of the INTERPRET table because the 'end of table'
  indicator (provided by the ENDINTAB macro) was not present.
  Placing the "ENDINTAB" macro before the Assembler "END"
  statement (as stated in the VTAM Resource Definition
  Reference manual) resolves the problem.
  Since the ENDINTAB macro is required to
  complete the INTERPRET table, the table should not assemble
  correctly if the ENDINTAB macro is missing (or not processed).
  

Problem conclusion

• This is a serviceability APAR.
  The INTAB macro has been changed to check for a new symbol,
  ISTENDIN, which the ENDINTAB macro will generate. If the
  ENDINTAB macro is not coded, (or is not encountered by the
  assembler), the assembly of the INTERPRET table will fail.
  This will alert the user that the table is not coded correctly.
