I'm new to Prolog and trying to do a program to check if some values can be a date, but I don't know what can I do with the language. I don't know the commands.
As example, I want to get the length of a string, but I don't know if this is possible.
Someone can show me a list of Prolog commands? I'm using tuProlog for Java.
By the way, the program I want to do is this: receive two or three parameters and check if is some type of date (eg.: 10/2000, 2011/09, 11/03/1191, etc.).
The documentation for SICStus Prolog describes its standard library. I'm not entirely sure what parts of it are or aren't standard for a Prolog implementation, but it might help you.
