How to use SPSS if condition for various variables?

Here the variable V4_15 is corralated to V4_15_0, V4_15_1, V4_15_2, V4_15_3, V4_15_4, V4_15_5, V4_15_6, V4_15_7.

If any of those later variables is 0 then V4_15 is 0 (Absent) and if any of those variables is 1 then V4_15 is 1 (present).

Any idea how can I do this using Transform > Compute variable?

I am a beginner level user.
