<<Disclaimer: Verify this information before applying it to your situation.>> According to Webster, pica is a craving for unnatural food. Could it be that PICA is an acronym for a disease or condition with a much longer name and that you are discussing two different things? Pica is also used in reference to type size, but I don't think that applies here. ;-) Jeannine Kantz [log in to unmask] College Station, Tx
