9.12 D - Date CommandsUse the DATE command to set the internal IBM 7171 date constant, or to displaythe current IBM 7171 date constant. Only decimal numerals are allowed.Format:I mm-dd-yyWhere:mm Specifies the decimal month, to be no larger than 12.dd Specifies the day, to be no larger than 31.yy Specifies the year, to be no larger than 99.The command D by itself is a request to display the current date constant D followedby a new date sets the internal IBM 7171 date constant to the specificationgiven.Note: The date command is intended only to be used as a relative time stamp forerror messages. It is not updated by the IBM 7171. The date constant is only asuseful as the user makes it. It is not intended to be a calendar substitute. It isrecommended that the user set the date constant as often as possible. Since errormessages are kept in a circular list, it would be almost impossible to determineexactly when an error occurred if the date constant were not changed.Example:D 6-30-84This command sets the IBM 7171 date constant to June 30, 1984. To verify thedate set, the Maintenance Facility will respond with:Current Date: 6-30-84Error Messages:Invalid Date Specification.9-14 IBM 7171 Reference Manual and Programming Guide
