The Change mode is used to correct a field in a record. Enter the letter "C" and the system will prompt for the record number and then display "Change no....". At that time enter the field number to be changed and modify the data. Field 1 and sometimes Field 2 cannot be changed, they are record identification fields, also known as "KEY" fields. For example, in the inventory system, the stock number cannot be changed because it is a Key field. If an item is given the wrong key number then delete the record and add a new record with the correct key field.
