barmenudata:
DATA Parameters
DATA The barmenu function  accepts two arrays
DATA as  parameters.  The first  contains the
DATA heading  names that  will  appear  above
DATA their  respective menu.  The second is a
DATA two dimensional  array  to  contain  the
DATA lists of items which  appear under their
DATA respective headings.,,,,,,,,,,,,,,

DATA Headings
DATA You may pass as many menu  headings
DATA as  you can  fit on  the  menu bar.
DATA you may  also pass  up to  22 items
DATA for each heading without shadows or
DATA 21  if you prefer shadows.  Barmenu
DATA returns  the  subscript  chosen and
DATA key  the  user  entered to  escape.,,,,,,,,,,,,,,

DATA Sizing
DATA The function automatically sizes
DATA everthing for you.  The  headers
DATA are spaced and the widths of the
DATA windows are set according to the
DATA widest item element.  The header
DATA bar filler character is variable
DATA to suit different styles.,,,,,,,,,,,,,,

DATA Auto-adjust
DATA If you like your menu choices to be  extremely descriptive -
DATA no problem!  The bar menu function will automatically adjust
DATA your sub-menu to fit asthetically under the menu label.   So
DATA use the whole screen if you wish!  Hit ESC or ENTER for menu.

scrolldata:
DATA The scrollmenu function allows the user to choose from a list
DATA of items which would not normally fit within the boundaries
DATA of a window.  The list may be as long as needed and the window
DATA may be as short as needed (minimum of one line).
DATA "                                                        MORE "
DATA "     Scrolling of one full window length is done with the PgUp"
DATA and PgDn keys.  the up and down cursor keys allow moving one
DATA line at a time.
