When using the chr function on values 127 and beyond, it appears to return only one value, as if the last char in the character set is 127. This is happening on a HP-UX running an Oracle 8.0. However, it gives a different result when tried with an aix system on oracle 8.0 [ I can go all the way upto 255 ]. I believe this has nothing to do with the oracle and unix system, but some setup for oracle is making this. Can you please tell me what is that setting that I am missing?
