Recode using if statement

[AZIQ1]

I want to create a new variable called new var 

conditions for recoding are:

if var1 = 'A' and all other var2 - var5 are blank then newvar = A;

if var1 = 'A' and any of the var2-var5 are B and nothing else in the vars (should be blank) then newvar = AB

if var1='A' and var2= 'R' then newvar but all other vars should be null or blank = AR;

VAR1	VAR2	VAR3	VAR4	VAR5	VAR6	Newvar
A						A
A	B					AB
A		B				AB
A			B			AB
A				B		AB
A	R					AR
A	B	R				ABR
A	R	R				ARR
A			R			AR

Basically I need help with how to tell if statement to make sure that the combination is correct provided all other variables are null.

Thanks

Is your second last record correct or should it be ARR?

[AZIQ1]

Yes it should be ARR.

Thank you.

That's an or question not a yes/no question. Please take the time to detail your question and answers otherwise why should we take the time to answer them.

Sorry, my bad, yes it should be ARR.

You should post samples that include what happen in other conditions, ie what if they're not blank.

Thank you - it should  be "unknown" if none of the conditions meet.

Thanks

What about 

x=CATT(of var1-var6);

Thank you so much.
