When prompting for CREATE TABLE, support is available for entering column definitions individually.
Place your cursor in the column definition section of the display, and press F4=Prompt. A display that provides room for entering all the information for one column definition is shown.
To enter a column name longer than 18 characters, press F20=Display entire name. A window with enough space for a 30 character name will be displayed.
The editing keys, F6=Insert line, F10=Copy line, and F14=Delete line, can be used to add and delete entries in the column definition list.
