This is called from COBOL. Transliterating it from HLASM to __efficient__ COBOL might be a wicked thing to do. But, IMO, the COBOL compiler does not generate the best assembler. And if it is nested, then every compile would need to use compile options which are correct for it. Also, any change would require a perhaps massive recompilation marathon. -- John McKown Systems Engineer IV IT Administrative Services Group HealthMarkets(r) 9151 Boulevard 26 * N.
