File Erase {R}←X ⎕FERASE Y

Access code 4

Y must be a simple integer scalar or 1 or 2 element vector containing the file tie number followed by an optional passnumber. If the passnumber is omitted it is assumed to be zero. X must be a character scalar or vector containing the name of the file associated with the tie number Y. This name must be identical with the name used to tie the file (except that the directory delimiters / and \ are treated as being the same) and the file must be exclusively tied. The file named in X is erased and untied.

The shy result of ⎕FERASE is the tie number of the erased file.
