=====Accessing files with no extension=====

//by Jon Ripley, May 2006//\\ \\  When using **OPENIN**, **OPENUP** and **OPENOUT** to create or access files that do not have a file extension the default action of BBC BASIC is to append a //.bbc// file extension. To create or access files with no file extension you must add a full stop to the file name.\\ \\  To **OPENIN**, **OPENUP** or **OPENOUT** a file called **MyFile** use:\\ 
<code bb4w>
        hfile% = OPENIN "MyFile."
        hfile% = OPENOUT "MyFile."
        hfile% = OPENUP "MyFile."
</code>
The same applies when accessing files with no extension using a //**star**// command or **OSCLI**:\\ \\ 
<code bb4w>
        *DISPLAY MyFile.
        *COPY MyOldFile. MyNewFile.
</code>
The default file extensions appended by the //**star**// commands or **OSCLI** when none is supplied are as follows:\\ \\ 

| *CHDIR (*CD)\\ | none\\ |
| *COPY\\ | .BBC\\ |
| *DELETE (*DEL, *ERASE)\\ | .BBC\\ |
| *DIR\\ | .BBC\\ |
| *DISPLAY\\ | .BMP\\ |
| *EXEC\\ | .BBC\\ |
| *GSAVE (*SCREENSAVE)\\ | .BMP\\ |
| *LIST / *TYPE\\ | .BBC\\ |
| *LOAD / *SAVE\\ | .BBC\\ |
| *LOCK / *UNLOCK\\ | .BBC\\ |
| *MKDIR (*MD)\\ | none\\ |
| *PLAY\\ | .MID\\ |
| *RENAME (*REN)\\ | .BBC\\ |
| *RMDIR (*RD)\\ | none\\ |
| *RUN\\ | none\\ |
| *SPOOL / *SPOOLON\\ | .BBC\\ |
