Kelley Johnston Ahh, amazingly concise for something designed to control print and batch queues and drive the occasional Autogen or ACMSGen.

Although I would probably have used beers :== "''beer'" + "''plural'" to show off the easy symbol handling. F$FAO is elegant, but there was a pure joy to mastering the use of DCL symbols.

Love DCL, wrote about a quarter-million lines of it...Ok, now I'm going to go look up VCL and ... maybe, just maybe, BLISS...
