FILE_SETKEY_
The FILE_SETKEY_ procedure supersedes the KEYPOSITION[X] procedures. The
FILE_SETKEY_ procedure is used to position by primary or alternate key within a
structured file, and sets the current position, access path, and positioning mode for the
specified file. FILE_SETKEY_ can be used with format 2 files.
FILE_SETPOSITION_
The FILE_SETPOSITION_ procedure supersedes the POSITION procedure. This
procedure has the same function as the POSITION procedure but the
FILE_SETPOSITION_ procedure accepts an 8-byte record specifier, enabling use with
format 2 files.
