Subject:      Perl match question. Using prxmatch to complete an if contains
              statement.

Hello all

I was this morning hoping to do this

If x_char contains 'y' then var =1;


Apparently I can not use "contains" in an if statement.

So I use this

If substr(x_char, prxmatch(x_char,'y'), 1) = 'y' then var=1;

My question is what does the prxmatch function return for a position number, if it does not find the string you asked it to find? In other words will my if statement cough up too many errors when observations of x_char do not contain a 'y' character?
