strings

[Mark Goland]

Hi All,

I have a tring which contains 60 to 80 keywords, I need to know what position a 
keyword is in. I need an efficint way to extra position of key words, here is how I am 
currently finding positions,

$string="type,model,color,date";

# this is how I am currently getting position, which is nto very efficiant
@keys=split ",",$string;
foreach( @keys ){
 $position++;
 last if m/model/ig;
}
