filename
Name of the file to be deleted
The file name can be specified with path and file identifier. Path names
must be absolute, that is, starting with "/". If the file name does not
contain a domain identifier (_N_), it is added accordingly. If no identifier
(_MPF, _SPF or _CYC) is specified, _MPF is automatically added. If
there is no path specified, the file is saved in the current directory
(= directory of selected program). The file name length can be up to 32
bytes, the path length up to 128 bytes.
Example:
PROTFILE
_N_PROTFILE
_N_PROTFILE_MPF
/_N_MPF_DIR_/_N_PROTFILE_MPF/
