Hi!!!

I am trying to perform operations inside the Arduino Uno for example:
Comparisons between 2 data A and B and result C by means of serial monitor 1 or 0, true or false.
all works fine as (<, <=, =,>,> =) works fine.
instead this (<>) I get an error why?
I have read with help at bascom to learn and practice.

Code:
$regfile = "m328pdef.dat"
$crystal = 16000000
$hwstack = 40
$swstack = 16
$framesize = 32

$baud = 19200

Dim A As Byte
Dim B As Byte
Dim C As Byte

A = 100
B = 100
C = A <> B



Do

 Print C
 Waitms 1000

Loop
End
 


It's wrong?

    Error : 93 Line : 37 Variable not dimensioned [A <> B] , in File : C:\Users\Bienvenido\Desktop\Proyecto_ Bascom_Arduino_ 2020\TIMER\Prueba.bas


Question Question Question Question Question
I am looking forward to your response.

C = A <> B


That puts two operators on the same line, which will confuse the compiler.

One approach would be:

Code:

If A <> B then
  C = 1
Else
  C = 0
End If

C = A = B
C = A > B
These arithmetic expressions put True[1] or False[0] of the calculation result in the variable C.

C = A <> B
The above is probably a BASCOM oversight or bug.

However, as JC says, it is possible to directly judge True or False by the IF statement, so the situation where this operator is used is limited.

You have to work but I don't know how strange I get Bascom error

Code:

Dim A As Byte , B As Byte , C As Byte

A = B = C
A = Not A.0

Very easy!!! I'm already learning!!!

Code:
$regfile = "m328pdef.dat"
$crystal = 16000000
$hwstack = 40
$swstack = 16
$framesize = 32

$baud = 9600

Config Pinb.5 = Output
Led_5 Alias Portb.5
Config Pind.2 = Output
Led_2 Alias Portd.2
Config Pind.3 = Output
Led_3 Alias Portd.3

Dim A As Byte : Dim B As Byte : Dim C As Byte

A = B = C

A.0 = Led_5
A.0 = 1

A = Not A.0


Do
   If A = 1 Then
    Print "Led_5_ON,Led_2_ON,Led_3_ON"
    Waitms 1000
    Set Led_5
    Set Led_2
    Set Led_3
    Else
    A = 0
    Print "Led_5_OFF,Led_2_OFF,Led_3_OFF"
    Waitms 1000
    Reset Led_5
    Reset Led_2
    Reset Led_3
   End If
Loop
End

e

A= Not A.0 ( A is not A dot zero)
What is de exact meaning of that dot (".") ????

EDIT:
I think I found it.
It is hard to find in the Help, but I got a hint at Set, Reset.
This is how I understand it:
A.0 means bit nr 0 of A.
A can be a byte or word.
The bit nr can be 0, 1, ..., 6, 7 in a byte, or 0, 1, ..., 14, 15 in a word.
