See my response to Peter; I can't control the format of that data string
(it's from a different application). I just need to split out the data
fields and store them away in a disk file. Or am I missing the point of
your suggestion?

thats ugly, why don't you tokenize it into string pairs, store the
pairs and works with them?

This code is part of a servlet running in TC 5.5.12, jre ver 1.5.0.6.
I use this code to break out individual data fields from a line which is
structured as "a=11111&b=22222&c=333333333&d=44444&e=5". It is
executed for over 2 million data lines per day, so this routine is
executed over 10 million times per day. All the fields are short ( < 10
chars) except the 5th one, which can be up to about 40 characters. Is
there a more cpu-efficient way of doing this, or is this about as good
as it gets?
private static String getField ( String fieldName, String
dataString ) {
Integer ii, kk;
ii = dataString.indexOf( fieldName + "=" );
if (ii == -1 ) return null;
kk = dataString.indexOf( "&", ii );
if ( kk.equals( -1 )) {
kk = dataString.length();
}
return ( dataString.substring( ii + 2, kk ));
}
TIA!
