I can not get the function index work correctly. The following code is in
the data step:
===================================
foo = 'ABCD';
bar = substr(plot, 6, 1);
x = index(foo, bar);
put 'plot=' plot 'foo=' foo 'bar=' bar x;
if index(foo, bar) = 0 then blk = 2;
else blk = 1;
==================================
and the following is from the log file:

plot=HDWDMABI foo=ABCD bar=A 0
plot=HDWDMABI foo=ABCD bar=A 0
plot=HDWDMABI foo=ABCD bar=A 0
plot=HDWDMABI foo=ABCD bar=A 0

I expected x to be 1 for bar=A, but is is 0. Could someone please point
out what I am missing?

Thanks,

Jun
