The redraw statement updates and redisplays one or more window fields.
redraw {field} field_name {, field_name, field_name...}
• field – An optional keyword identifying field_name as a field.
• field_name – The name of the field to be redrawn. Multiple fields can be redrawn using one redraw statement by listing each field’s name, separated by commas.
For performance reasons, list items such as list boxes and combo boxes aren’t automatically redrawn when new strings are added to the list with the add item statement. All additions to list fields made while a window is open should be followed by a redraw statement.
