I'm not a menu user but in syntax one approach would be:

COMPUTE V3 = V1 + V2*2 + 1 .

Where:
 V1 is first variable (0,1,missing)
 V2 is second variable (0,1,missing)
 V3 is new computed variable (1,2,3,4, missing)

If either v1 or v2 are missing, COMPUTE will assign v3 to be missing.

Subject: Combining binary columns into a single column

Dear SPSS users

I would be most grateful if I could obtain advice on an efficient
menu-based method within SPSS for coding the pairs forthcoming from two
'binary columns' into a single column after the following fashion:

0,0 -->1
0,1--> 2
1,0-->3
1,1-->4
1,blank-->blank
blank,1-->blank
blank,blank-->blank

Thank you in advance for your kind assistance.

Best wishes

Margaret
