43 | complex features were intentionally left out. In addition,
44 | ee is intended to be compiled by people with little computer
45 | experience, which means that it needs to be small, relatively
46 | simple in implementation, and portable.

231 | The following structure allows menu items to be flexibly declared.
232 | The first item is the string describing the selection, the second
233 | is the address of the procedure to call when the item is selected,
234 | and the third is the argument for the procedure.
236 | For those systems with i18n, the string should be accompanied by a
237 | catalog number. The 'int *' should be replaced with 'void *' on
238 | systems with that type.
240 | The first menu item will be the title of the menu, with NULL
241 | parameters for the procedure and argument, followed by the menu items.
243 | If the procedure value is NULL, the menu item is displayed, but no
244 | procedure is called when the item is selected. The number of the
245 | item will be returned. If the third (argument) parameter is -1, no
246 | argument is given to the procedure when it is called.
