Rethinking your idea a bit...Suppose the switch jump_address[] array was really an array of hardcoded jmp instructions, 5 bytes each:
jmp_table:
jmp Lcase1;
jmp Lcase2;
jmp Lcase3;
...
and then the switch(EBX) would be:
lea EAX,jmp_table[EBX][EBX*4]
jmp EAX
is that kick-ass or what?
(There'd be some additional complication for PIC code.)
