how do I use TCharacter (or any other library)
« on: May 27, 2022, 10:46:46 pm »
beginner here, sorry for asking stupid question. I am trying to check if user input string is a number, and found this easy IsNumber function. But when I include it in my code it does not compile, compiler doesn't know this function. How does it work? I installed FPC only a few months ago.
