Recipes

I type all my recipes into the computer, and tweak them each time I make them. I published a collection once before, but I am now releasing for the first time the full database. Obviously, it is a work in progress, but this link should update automatically:

Windows FileSearch

Windows FileSearch (used in FindFirstFile, etc): ? matches 0 or 1 characters; * matches 0 or more characters. The . does not match any . but only signifies the delimiter between name and extension - it is automatically supplied on the right if lacking.

Bug: If a string contains * anywhere on the left of the extension and exactly three characters in the extension, it adds implicit * at end of string, thus matching files with longer extensions.
