- Dear Gerald
-
- I have followed your Friday 13th competition with interest, especially
- Robert Macmillan's claim to be both shortest and quickest. I would not
- usually enter but have a look at the enclosed "Fridays" sheet.
-
- I do not know how you should time it but if you set AutoRecalc off,
- load the file and then Recalculate it takes 1 min 17 sec on my A5000 in
- a high-resolution mode, a good bit less in Mode 0.
-
- As for shortness, it depends on how you look at the problem. This
- solution requires only one piece of data in A1 and two formulas in A2
- and B1 which are replicated, but it does use a lot of rows!
-
- There are a few changes that can run faster or make it more readable
- but overall I prefer this version.
-
- For sheer speed a separate Basic program wins hands down. The file
- "FridaysB" takes about half a second, most of which is spent filling an
- array with the month lengths and printing the result and it still does
- not use any programmer's tricks to speed it up.
