bit position variable

[dsicon]

i have some code like this:
'***********
WriteByte var byte 'WriteByte holds the on off states for 8 LEDs
LED32 var byte 'LED32 holds the bit position for LED32 on the pcb in the WriteByte byte

LED32 = 3 ' bit3 in WriteByte, LED32 is connected to bit3 of a port expander chip, not a PIC pin

WriteByte.3 = 0 'this turns on LED32 but is not very readable
'*************

but the above code is not very readable, i would like to write:
WriteByte.LED32 = 0
but above statement throws a compile error

what is the best way to handle this ? sadly, i think i used to know, an array ?

I think this is what you are getting at.

WriteByte    VAR BYTE
LED32        VAR WriteByte.3

LED32 = 0

But, lets say that this LED is actually attached to pin 3 of PORTB. In this case, you could use this:

LED32        VAR PORTB.3

Or this:

WriteByte    VAR PORTB
LED32        VAR WriteByte.3

you seem to be suggesting that this is simpler than i am making it

you might be correct, let me play with this and get back to you and thanks for your response
