More recently, the topic of letter-shift words was reopened by Dave Morice (who exhibited an analogue device for more quickly finding such pairs) and Anthony Sebastian (who showed how it could be done using a spreadsheet program). About the only thing Sebastian's method for finding letter-shift words can do for a logologist is give him eyestrain. In fact, computer facilities require for the job are less than needed for the spreadsheet. I wrote a program in QUICKBASIC 4.0 which attacked the problem as follows:
