Here is an 8 bit pointer: char table[255]; char pointerInTable; Now, "pointerInTable" points to any position within that table. For instance to get the contents of position 154: pointerInTable = 154; val = table[pointerInTable]; Using this (in plain C) you can have pointers of any size. Want a 10 bit pointer? Easy. char table[1024]; int pointerInTable; /* Values from 0 to 1023 */ >> is it possible using that stack for call of function as >> f(a, b)<=> push32 b|push32 a| call32 f > > Not on my system which doesn't use a stack or have a push instruction. > Ahh OK; > You shouldn't believe everything you read on Usenet. > You are right. I don't believe you that there isn't (by convention) a register pointing to the stack, and that sub stack,8 move value,[stack] doesn't work. Which system are you using?
