Christian husband, father, grandfather who loves food, reading, tivo, web surfing, talking. Over the years, I've dealt with Apple II DOS, ProDOS, various DEC OSes, MVS, SunOS, Ultrix, Solaris, Windows NT, Windows XP, Windows Vista, and various others that I've conveniently forgotten for the moment, as well as BASIC of a dozen or more variants, BAL, PL/I, C, sh/ksh/bash, awk, perl, Tcl, DOS .bat files, HTML, XML, and various other constructs that can cause one sleepless nights.
