IST453I
parameter PARAMETER VALUE value NOT VALID

Explanation

VTAM® issues this message when parameter was specified on an operator command and is not valid. value is the first 17 characters of the value specified for parameter. If no value is displayed for value, then the value of the parameter specified was of zero length (e.g. NETID=).

Possible reasons for this message include:
  • If the value specified for parameter is a network name, the name might be undefined or the resource might be inactive.
  • If the value specified for parameter is a network name, and IDTYPE was also specified on the command, this message can be displayed when:
    • The network name parameter does not exist.
    • The network name parameter might be correct, but does not exist with the IDTYPE that was specified on the command.
Notes:
  1. The parameter might be valid for other combinations of parameters and resource types or might have been omitted when required.
  2. Parameters on operator commands are not processed in the order they are entered on the command.
