The /did command
The /did command allows you to modify the values of controls in a dialog, eg. changing the text in an edit control, or setting focus to a button, or deleting lines in a listbox.
init just before a dialog is displayed, controls can be initialized in this event. id is zero.
-r clear all text in id
-a add line of text to end
Straight from the help file itself no clue why it wont work
