Yes I know. I've read two textbooks cover-to-cover on macro processing: A J Cole's - Macro Processors http://www.computinghistory.org.uk/det/34593/Macro-Processors/ (Prof Cole was the Comp Sci prof at St Andrews University, in Scotland, where I'm ashamed to say I didn't work very hard, but sang in lots and lots of choirs. I bought and read most of my textbook collection after graduating.) P J Brown - Macro Processors and Techniques for Portable Software http://www.computinghistory.org.uk/det/10153/Macro-Processors-and-Techniques-for-Portable-Software/ (IIRC Peter Brown was a prof elsewhere - Univ of Canterbury? - and I do remember him coming as a visiting lecturer.) -- Jeremy Nicoll - my opinions are my own. ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: INFO IBM-MAIN
