GT.M uses standard OpenVMS file-specifications for device specifiers.

The complete format for a file-specification is:

    
    node::device:[directory]file.filetype;version
    
    
    

If the expression specifying a device does not contain a complete file-specification, the expression may start with a logical name that translates to one or more leading components of the file-specification filename. GT.M applies default values for the missing components.

The GT.M file-specification defaults are the following:

Node: Current user node

Device: Current default OpenVMS device

Directory: Current default OpenVMS directory

Filetype: .DAT for the file extension

Version: Latest version number
