Jonathan, Having recently put up with other languages' so-called macro features, I continue to marvel at the power and flexibility of HLASM.
Many years ago, Dr. Ehrman & I made up some buttons that we distributed at SHARE with a variation of a clause in the 1st amendment of the U.S. Constitution: "The right to ASSEMBLE shall not be abridged!" You continued to uphold the standard of excellence that Dr. Ehrman put into HLASM, and your expertise will be sorely missed. It was a privilege and pleasure to work. Best of luck in all your future endeavors.
