Very basic help please

[Russlk]

In my program, the statement: let portb = h is flagged as an error. Port b is an output, why can't I program it the same as portc? My program:
REM INITIAL CONDITIONS
#picaxe 28x1
LET PINS = %00000000 REM MAKE ALL OUTPUTS LOW
LET DIRSC = %11111111 REM MAKE PORT C ALL OUTPUTS
LET PINSC = %00000000 REM MAKE ALL OUTPUTS LOW
SYMBOL H = B1
SYMBOL M = B0

START:

FOR H = 1 TO 12 REM HOUR LOOP
FOR M = 1 TO 12 REM MINUTE LOOP
IF PORTA pin0 = 1 then GOSUB SETMIN REM TOGGLE SWITCH TO SET MINUTES
IF PORTA pin1 = 1 then GOSUB SETHR REM TOGGLE SWITCH TO SET HOUR
LINE1: PAUSE 60000 REM PAUSE 1 MINUTE
IF PORTA pin2 =1 THEN LINE3 REM THIS MAKES A ONE MINUTE ADJUSTMENT
' TO INCREMENT THE MIN. LED EARLIER
PAUSE 60000 REM PAUSE 1 MINUTE
LINE3: PAUSE 30000 REM PAUSE 30 SECONDS
LET PORTC = M REM INCREMENT THE MINUTE LED
PAUSE 60000
IF PORTA pin2 = 1 then PAUSE 60000 REM THIS MAKES A ONE MINUTE ADJUSTMENT
' TO INCREMENT THE MIN. LED LATER
PAUSE 60000
PAUSE 30000
NEXT M
LET PORTB = H REM INCREMENT THE HOUR LED
NEXT H
GOTO START REM REPEAT FOR ANOTHER 12 HOURS

try pins = h instead of portB = h

Russlk,

Firstly welcome to the PICAXE forum.

Svejk has given you the solution.

Port B is the standard ouput port for the 28X1 and thus there is no need (or ability) to refer to that group of output pins as port B
Have a look at page 113 of the PICAXE manual 2 (V6.9). It is ether pins or pinc

Set/clear all outputs on the main output port (let pins = ). <=== This port B by default
Set/clear all outputs on portc (let pinsc =)

Good point Westy,

However, why the inconsistency?
Have previously suggested to Technical that they 'retrofit' PE to the X2 family port.pin syntax for all chips as an optional syntax.
Similarly a retrofit of a consistent handling of the pins/pinc/portX as an optional syntax would avoid the repeat questions and frustration to users of these areas for confusion.
