I have to disagree with those three, but I see no point in continuing. Maybe, I should've described the 5MLoc application in more detail ... It was a RT (real-time) OLTP (online transaction processing) application with transaction protection which used with a 3rd party, fault-tolerant, in-memory database/ramdisk, all executing on fault tolerant, redundant hardware (Stratus Continuum 600 series). The code was in PL/1. PL/1 is Stratus' standard compliant version of early PL/I. It was an internal company application which handled the brokerage's stock trading for NYSE and NASDAQ securities. It handled four T1's of continuous, incoming quote feeds and other securities data in real-time. This was circa year 2000. Rod Pemberton
