what is different form, follow as:
(1)code XBYTE *AA[]={...}; (2)code void (*BB[])(void)={...};
"the coding above is not realizing." Sorry, what do you mean by that? Do you mean that it doesn't compile? If so, there's probably a fault in your definition of XBYTE. If you're using the standard Keil definition of XBYTE, then it will never compile - read the description of XBYTE in the C51 Manual.
