The end of the list is marked with P1=111. You can also access the text for a specific item in that

the "n" to read the name of the index. For example:

(bRU! "left side, R")
(bRU?n6)
(bRU! "Top left Corner, R")
ConTRol TYPe: To find out the type of control it is that you are using, add the letter "T" to your

parameter after the "T" to find out the type of control that the index is. For some slide bar or number
controls, an additional parameter may be returned to specify the number of decimal places the
control uses and if the control is to be displayed as a percentage (0=min and 100=max). If the
reply message does not contain the letter "T", than this function is invalid for that control.
