The file management functions allow 4gl developers to manage files and directories on the application server. You are able to find the file name from a given path and similarly you can find just the directory from a given file path. You are also able to create and remove directories and paths on the server side.
fgl_mk(file_name)
This function creates a file at the path passed to it. It returns TRUE on success and FALSE on failure. Again, it will create the file at the current working directory, unless told otherwise:
fgl_mk("/docs/Help")
would create the Help file at /docs/.
When you specify a file name, be careful with its case.
UNIX is case-sensitive, so it will treat files which names come in different cases as separate files.
