computing new variable again

[Jean Hanson]

I received some  great help yesterday with the following syntax

 

vector v=OCC_P to ILIUM_P.

compute UIV_P=0.

loop #i=1 to 29.

do if v(#i)=1.

compute UIV_P=#i.

BREAK.

end if.

end loop.

 

But now I want to do the reverse and calculate a variable starting from the bottom of the vector. I tried the following, which did not work.

 

vector v= OCC_P to ILIUM_P.

compute LIV_P=0.

loop #i=29 to 1.

do if v(#i)=1.

compute LIV_P=#i.

BREAK.

end if.

end loop.

 

In advance thanks for the help.

Hi Jean,

Try this:

vector v= OCC_P to ILIUM_P.

compute LIV_P=0.

loop #i=29 to 1 BY -1.

do if v(#i)=1.

compute LIV_P=#i.

BREAK.

end if.

end loop.

Best regards,
Beata
