Asking a writer to be brief is like asking a turtle to be quick. Only 500 chars? Well, here goes. I wrote 3 books on computer programming that were published by SAM'S. I've been a regular columnist for technical journals, and have published various and sundry articles. Currently I am working on the plot for a historical mystery. Groucho Marx said, "Outside of a dog a book is a man's best friend. Inside a dog it is too dark to read." So go make a friend and read a book. Eric in Pacifica CA
