“Autoclear” status of a form field. Indicates whether existing data is automatically cleared from a form field when new data is entered.
A 1-character code, as shown in the table below:
|Y||The field is to be cleared automatically when the end-user begins to modify it for the first time|
|N||Existing data in the field remains when the end-user begins to modify the field|
AC defaults to N, except for text-entry form fields with an N (numeric) data type (DT), which force an autoclear status of Y.
If AC is set to Y, the text will be selected when the end-user enters the field. Typing new text will replace the selected text. Typing Delete or Backspace will erase the text. Pressing an arrow key will deselect the text.
