The $Curfile function returns the name of the file from which the current record has been selected. If the file is remote, $Curfile also returns the location of the file (in the form filename AT location). $Curfile takes no arguments.
You can use $Curfile in two places:
- In arithmetic and Print specifications within a record loop
- In an In clause to override a default file or group in a Store Record statement
See $CURFILE and $UPDATE functions for a discussion of default files and for examples of requests using $Curfile.
You cannot use an In clause that includes both Member and $Curfile. See IN GROUP MEMBER clause for more information about the In Group Member clause.

- The CURFILE parameter.
Note: In general,$Curfileis better than$View('CURFILE'). - The DEFCNTX parameter (which is quite similar to CURFILE but provides more information) and the APDFCNTX parameter.
- The DEFAULT and OPEN commands, which reset the file/group context.
- The OPENC command does not reset the file/group context.
- The CLOSE command, which might reset the file/group context.
