[Sdcc-user] cooking with pointers

[<e....@wo...>]

Hi list,

I have some problems with the code below.

The idea is to have a common function, interpreting a given set of char commands, working on a structure, providing it with the command-string, the number of commands and an array with pointers to the functions 
to be called. :)

Ok, more slow...

I have a structure defined like this

struct menu_struct
{
  char *commands;              // string of chars
  byte count_of;               // ... them
  void (*(*what_to_do)[])();   // guess what it should be :)
};

just as a typedef in a global headerfile. In the sourcefile I have

struct menu_struct *a1;

to have a pointer to such a structure. Initialized such a structure like this

code struct menu_struct Root={
  "123456",
  6,
  Level0
};

where Level0 is defined like this

code void (*(Level0)[])()={
  funktion1,
  funktion2,
  funktion3,
  funktion4,
  funktion5,
  funktion6
};

the funktions are defined somewhere in the same sourcefile and prototyped properly. Pointer a1 is initialized like this

void init_command(void){
  a1 = &Root;
}

The command interpreter goes like this

void command(byte cmd){
  byte i=a1->count_of;

  do{
    if(a1->commands[--i]==cmd){
      (*(a1->what_to_do)[i])();
      // Here comes debugging stuff
      Disp_dec(cmd);
      Disp_char(a1->commands[i]);
      break;
    }
  }while(i);
}

My Problem:
It always finds the correct command in the command-string after the right number of loops AND it calls a function out of the array BUT it calls ONLY the first function "function1", even if I give him a '6' or a '1' or 
whatelse.

Please give me a breakthrough or at least an idea where am I could be blocked @:?
