I'm trying to make a scripting language with notepad like I did with my DarkBASIC game. I want these TXT scripts to open other TXT scripts with a "callscript" command in notepad. In DarkBASIC, I did this with the "file open" to check to see if a file index is currently open.

In AppGameKit, I'm trying to use the "fileIsOpen" command, but I get the error message: "File 1 does not exist". I thought the command was to check whether the file is open in the program or not. Is there some other command that I'm missing? I want a command to check whether the current file index is open in the program so I can keep track of nested scripts.

Thanks.

I want to test it when it's not open, though. And it says, "File not found".

EDIT: I'm not sure what the point of the command is. It's supposed to test whether a file is open or not, and if it's not open, it crashes the program. Pretty sure it's AppGameKit bug. I will probably have to work around it with variables.

This is one of the commands where you need to change the error mode before executing to prevent a stop error. For whatever reason(s), if the index doesn't already exist, it will stop your app to report it. So instead of just the command by itself, just preface with the error mode change, the restore the error mode after the check:



So 'FileState' will be 0 if it truly isn't open without stopping your app/game, or 1 if it does exist and is open.

I think that command will tell you if a particular file handle is open.
If the same file is opened using another handle it won't report that
