Subject: about the behavior of INDEX function

Hi,

I have a dataset have a string variable named 'ax' like

';1;' ';8;16;'

It begin and end with a ';' and all number seperated by ';'

syntax like

COMPUTE i1=INDEX(ax,';1;').
  IF (i1=0) i1=INDEX(ax,';1 ').

set i1 to 0 when ax is ';4;8;16;'

Can anyone know why?

Thank you

Jun
