os.Path.isfile
os.Path.isfile() method is used to check whether a file is a regular one or not:
CALL os.Path.isfile(f_name) RETURNING result
where
- f_name is a STRING variable containing the name of the file to check,
- result is TRUE if the file is a regular one or FALSE otherwise.
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.
