var=PINx dynamic

To read a port one writes a statement like

MYByte = PINA
or
MYByte = PinC.3

Is it possible to have the C and the 3 be variables?

like MYByte = Readpin Port_Number . bitnumber
Where Port_Number and bitnumber are Varibles?

For what chip because any may be addressed differently....Mega Xmega? Offset?

I dont investigate it but it is obvious that you cant set PINx.... you can only set PORTx or DDRx

only the BIT part can be used with a variable.
The port part is not variable but you could make a function for that.
In the Xmega it would be simple, while in the normal AVR all the ports have different address.

Hi,
I can't imagine what you need it for. Perhaps I can only think of creating a library. It works for output values and I used it but not in Bascom. I assume Bascom assigns translation registers based on the processor's def file. If you would like to do so you can assign the registry address of your variable to the beginning of the program and then work with it. But there is an unpleasant complication in losing the direct address option and turning it into an indirect one. So the advantage of In,Out,SBI,CBI will be lost to you.
