This routine offers a very simple way to invoke a fully-GUIfied alternative to the TI-BASIC Menu( command. The user can specify an icon, window location, title, and list of items and labels. Just like Menu(, the sum(13) command will Goto a specific label corresponding to the item selected, or return an error if no such label can be found. An alternate mode has been added in which if the LABELLIST is omitted, then the index of the chosen menu item will instead be returned in Ans.

Technical Details


X: X-coordinate of top-left corner of small window
Y: Y-coordinate of top-left corner of small window
ICON: 10-character hex string defining a 5x5 icon
TITLE: A string to be used as the window title
ITEMLIST: A list of items to be in the menu. Each menu item should conclude with the Stats Plots "+" symbol (in [2nd][Y=][>][>][2]), so the ITEMLIST string should contain as many Stats Plots "+" symbols as items.
LABELLIST: A string of 2*(number of items) characters. Two-character labels, like AA or Q2 or PA, are represented verbatim. One-character labels such as A or U are represented as a two character string, where the first character is a space, such as " A" or " U". Take a look at label E in the sample below for another example. If this argument is omitted completely, then no Goto'ing will be attempted; instead, Doors CS will simply return the index of the chosen menu item.


If the LABELLIST is specified, this routine will not modify Ans, but will Goto to the label corresponding to the chosen menu item. If the LABELLIST is instead omitted, Ans will indicate which item was chosen.
