IST1075I
PARAMETER n FOR option IS NOT VALID

Explanation

VTAM® issues this message during START processing or in response to a MODIFY VTAMOPTS command when the nth parameter specified for start option option contains a value that is not valid.

System action

VTAM ignores option.
  • If the error occurred during START processing, VTAM will issue message IST1311A to prompt you for the correct value of option.
  • If the error occurred in response to a MODIFY VTAMOPTS command, processing continues.

Operator response

  • If the error occurred during START processing, reenter all values for option in response to IST1311A. You can also enter a blank if you want to accept the default value for option.
  • If the error occurred in response to a MODIFY VTAMOPTS command, ensure that you entered option correctly.

System programmer response

  • If the error occurred during START processing, correct the value for option if option is coded in an ATCSTRxx file.
  • If the error occurred in response to a MODIFY VTAMOPTS command, no further action is required.
