Modifies the width of an item. The AML then prompts the user to enter the new desired item width. A valid answer must be greater or equal to the maximum length computed above. To modify an item and keep its position in the file, the AML runs through a loop on all the items.
Nothing is done on the items other than the one specified.
The program determines the item's definition, moves the item to a temporary item, drops it, recreates it, gets the data back from the temporary item and drops the temporary item. The program allows only C, I or N item types to be modified. When applied to numeric items, it returns the item width, regardless of how big the largest number is. This AML prompts the user for the new item width.
