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.
