Syntax

FILEEXIST(filename)

filename: specifies a physical filename of an external file. In a DATA step, filename can be a character expression, a string in quotation marks, or a DATA step variable. In a macro, filename can be any expression.

Under UNIX System Services (USS), filename can specify a path.

FILEEXIST returns 1 if the external file exists, and 0 if the file does not exist. FILEEXIST can also verify the existence of a directory in USS.
