Another way to change is to export the field using option write_my_kmt which saves to file kmt.dta under formatted control. Formatting is determined by the model's deepest level. File kmt.dta can then be edited with any text editor. Care must be exercised when editing so as not to change the format. If a character is deleted, a space or another character must be inserted in its place. When finished, the field can then be imported with option read_my_kmt.
