I don't understand what means "the available includes files" ?
An include file is a file containing programming code that is available for including in larger programs. The purpose behind this is to avoid rewriting code for different programs. Instead of writing each program from scratch, you can include include files to handle things that someone has already written code for. When writing GAME Code, you can use the include command to include the code in a particular include file. These are written as text files and have the .txt extension, which is the default extension for text files. But they are normally included without including the extension in the file name. The include files I have written are all in the /play/pbm/includes/ directory. To include one with the include command, just give its base name, which is the part before the .txt extension. H. G. Muller has written some include files in a different location, and these, I believe, are included by giving its full path and file name.
