COMMAND ERROR DESIGNATING SYSTEM

PURPOSE:To easily and effectively perform a reinput in the case an input character string including a command has an error by using an error area designating means which sets a cursor at the position shown by the error position information obtained via a command analyzing means or a command executing means. CONSTITUTION:An abnormality cause display means 6 displays the error cause obtained via a command analyzing means 3 or the abnormality cause obtained via a command executing means 5 on a display screen of a terminal equipment 1. An error area designating means 8 shows a character string including a command and inputted from the equipment 1 on the screen of the equipment 1 in a reinput enable form. At the same time, the means 8 sets a cursor at the position shown by the error position information obtained via the means 3 or 5. Thus it is possible to easily and effectively input again a corrected character string in the case an erroneous character string is inputted.
