- There were a few bugs with XMENU version 1.02. Here's the corrected
- version.

- * of this software.

- * in its entirety. The user cannot be charged, in whole or

- ************************************************************
- *
- * ACKNOWLEDGEMENTS:
- *
- * Thanks to Conan J. Fee whose XPNDR program inspired me to
- * finish writing XMENU and Detlef Muller for his
- * participation in writing XPNDR.
- *
- * Also, thanks to Todd Eckrich for his help in debugging.
- *
- ************************************************************
- *
- * The expanded menu program displays a menu using as many as
- * four rows at a time with the top four rows of keys
- * corresponding to each row of menu labels. This will
- * normally be enough to display all rows of a built-in menu.
- * If a menu contains more than four rows, a scroll indicator
- * will be displayed in the status area. Pressing ENTER will
- * advance the menu screen one page. Likewise, [ORANGE]-
- * ENTER will decrement the menu screen one page.
- *
- * Pressing a key in the top four rows that corresponds to a
- * menu label will immediately evaluate that menu item.
- * Pressing any non-menu key will cause the 48 to beep.
- * Pressing [ON] exits XMENU.
- *
- * Menu tree structures are supported. When a menu key
- * creates a different menu, it is nested below the parent
- * menu. Pressing [+/] will exit the sub-menu and restore
- * the calling parent menu. Likewise, pressing [BLUE]-[+/-]
- * will exit all sub-menus and restore the top most menu.
- *
- * Because the VAR menu is unique in the fact that the
- * contents of the menu can change by moving into a sub-
- * directory, but the menu definition doesn't actually
- * change, UPDIR has been assigned to [ORANGE]-[+/-].
- *
- * In addition to the menu display, XMENU also displays as
- * many line of the stack as possible using the medium font
- * size. A total of six lines are used for both the menu and
- * stack. If the menu only uses two lines, four will be used
- * for the stack.
- *
- * Most menus are defined by a list or a program that
- * generates a list. This data list is used by the built-in
- * menu commands to load the touch table (menu key bindings).
- * But several menus, like the VAR menu, are defined by a
- * list. Instead, they load the touch table themselves, on
- * the fly. Because it is difficult to determine how many
- * display lines will be needed for these menus, XMENU always
- * allocates four. The only built-in menus that are forced
- * to four display lines are VAR, LIBRARY, PORT0, PORT1,
- * PORT2, and any library menu.
- *
- * The following criteria was used when writing this program
- *
- * 1) Self contained
- * XMENU had to be a self standing program, not a library
- * or a directory.
- *
- * 2) Minimal amount of time writing
- * I don't really have much free time so I tried to keep
- * it simply. Very little time was spend trying to pack
- * the code. I did try to document it enough so someone
- * who is familiar with RPL can follow it though.
