**************************************************
|
|
* Auto-menu item macros *
|
|
* This is one alternative for defining a menu *
|
|
* item. It has the advantage of letting you *
|
|
* include specifiers for Bold, Italic, etc. *
|
|
**************************************************
|
|
|
|
*-------------------------------------------------
|
|
* Syntax:
|
|
* ]mnum = 0 ; initialize menu # at startvalue-1
|
|
* Menu ' Menu 1 '
|
|
*
|
|
* (See Menu macro, defined later....)
|
|
*
|
|
* ]inum = 255 ; Menu item starts with #256
|
|
* Item ' Choice 1 ';Kybd;'Bb';Check
|
|
* Ch1 = ]inum ; Set label Ch1 if somewhere else
|
|
* needs to use this item #.
|
|
* Item ' Choice 2 ';Disable;'';Kybd;'Cc'
|
|
* Item ' Choice 3 ';Divide;''
|
|
*
|
|
* Menu ' Menu 2 '
|
|
*
|
|
* Item ' Choice 4 ';Bold;'';Check
|
|
* Item ' Choice 5 ';Italic;'';Blank
|
|
* Item ' Choice 6 ';Underline';Kybd;'Dd'
|
|
*
|
|
* IMPORTANT: ALL items, except for Check and Blank, are followed by a second
|
|
* value. For the Kybd item, the ASCII characters follow in single quotes, Ex:
|
|
* Kybd;'Cc' (specifies Apple-C as an equivalent).
|
|
* All other items use a null 2nd value, as in:
|
|
* Italic;'' or Divide;'' etc.
|
|
*
|
|
* The variable ]inum MUST be initialized for the value of your first
|
|
* menu item MINUS 1 before using the first Item macro.
|
|
*
|
|
* Check or Blank, if used, MUST be the last item in the macro line.
|
|
*
|
|
* There can be up to three parameter pairs after the item name.
|
|
*-------------------------------------------------
|
|
* The point of all this is that rather than hard-
|
|
* code menu items values and subsequent references
|
|
* to that number when disabling menus, etc., this
|
|
* lets you add and delete menu items at will,
|
|
* and have labels like Ch1, etc. above, auto-
|
|
* matically set for the correct value during the
|
|
* assembly.
|
|
*-------------------------------------------------

|

|
|
|
|
Bold = 'B' ; bold menu item
|
|
Disable = 'D' ; disabled menu item
|
|
Italic = 'I' ; italic menu item
|
|
Underline = 'U' ; underlined menu item
|
|
Divide = 'V' ; menu dividing line
|
|
ColorHi = 'X' ; color hilite menu item
|
|
Kybd = '*' ; keyboard menu equivalent
|
|
Check = $1243 ; menu item with checkmark
|
|
Blank = $2043 ; menu item with blank
