I have PortA on an 18F8722 defined as an input port , and I want to read 3 of these pins at once. Say I want to read 0,3,5 and use the input in an IF statement is this possible?

You can check for a state on all 3 pins with one if statement if thats what you mean
In that example 0 and 3 must be high and 5 must be low to execute the code in the if statementCode:if porta.0=1 and porta.3=1 and porta.5=0 then
endif
I know I can do it that way I was just looking to do it with out the and satements... so I can say something like:
Code:IF PortA135 = $6h then
endif
IF ( PortA AND %00101001 ) = $29 (in this case all bits must be logic high) THEN whateverQuote:

That is also possible. You can use the bit AND operator (&).
The purpose of (porta & %00010101) is to strip out the unwanted information. Only the bit where you see a 1 will be kept from porta. Then you compare that with the value you are looking forCode:if (porta & %00010101)=%00010101 then
Edit: Looks like skimask got there before me!
