How to use "for" functions with analog inputs

Projects Programming
1

Hi
I want to set up the analog inputs as digital usig funcion "for". Further in the program I'm going to read from them.
To set up the digital ports I use:

for (int J=0; J<14; J++){
    pinMode(J, INPUT_PULLUP);  // initialize control over the keyboard:
  }

I want to do hte same with analog ports but does not work

for (int J=0; J<6; J++){
    pinMode(A J, INPUT_PULLUP);  // initialize control over the keyboard:
  }

Further on I read from digital

for (int J=0; J<14; J++){
    char reading = digitalRead(J);

and I want to read from A0 to A5 in the same manner
Can I ask for an advice? Any help appreciated

Just used the pin numbers 14 to 19 to access the analogue pins as digital ones.

Thanks Mike
I will try this

An AVR Port is a set of 8 pins that you can read/write/control together.

Every pin has a number. Mike just gave you a clue about which numbers are the analog pins.
Arduino pin numbers are not all the same as the chip pin numbers because the board traces don't all end up in the same order as the chip pins.

A pin map for each Arduino can be found through the product page for each Arduino board.
Here's the products page:

Here's the UNO/Deumilanove pin map page, the 168 maps the same as the 328:

So I now where i was making mistake.
I use Leonardo which has digital pins 0 to 13 so I assumed that the analog ones A0 to A5 will be assigned as 14-19. It appeared that A0 corresponds to pin 18 A1-pin 19 .... Looks like port 14, 15 is to be found in ICSP socket.
I did it in a wrong way - i should introduce my project first. I try to create CNC control panel which will send Keyboard shortcuts to Mach 3. Hardware is relatively done and now i write the soft for it.
Anyway, thanks for all help and quick reply.

Okay, finished kicking myself over no the pin map doesn't number Arduino analog pins. (had to realize that myself)

And I had a thought and tried it out, assign the pins as A0, etc, to an array for clarity/portability.
The same array can hold digital pins, this just shows that the names A0, etc, compile to numbers.

const byte  analogPins[ 6 ] = { A0, A1, A2, A3, A4, A5 }; 

void setup( void )
{
  Serial.begin( 9600 );
  
  for ( byte i = 0; i < 6; i++ )
  {
    Serial.println( analogPins[ i ] ); 
  }
}

void loop( void )
{
}

Which on the UNO lists 14 to 19.
