FILE()
Determine if files exist in the CA-Clipper default directory or path
------------------------------------------------------------------------------
Syntax
FILE(<cFilespec>) --> lExists
Arguments
<cFilespec> is in the current CA-Clipper default directory and path.
It is a standard file specification that can include the wildcard
characters * and ? as well as a drive and path reference. Explicit
references to a file must also include an extension.
Returns
FILE() returns true (.T.) if there is a match for any file matching the
<cFilespec> pattern; otherwise, it returns false (.F.).
Description
FILE() is an environment function that determines whether any file
matching a file specification pattern is found. FILE() searches the
specified directory if a path is explicitly specified.
If a path is not specified, FILE() searches the current CA-Clipper
default directory and then the CA-Clipper path. In no case is the DOS
path searched. Note also that FILE() does not recognize hidden or
system files in its search.
Examples
. In this example FILE() attempts to find Sales.dbf in other
than the current CA-Clipper default:
? FILE("Sales.dbf") // Result: .F.
? FILE("\APPS\DBF\Sales.dbf") // Result: .T.
//
SET PATH TO \APPS\DBF
? FILE("Sales.dbf") // Result: .T.
//
SET PATH TO
SET DEFAULT TO \APPS\DBF\
? FILE("Sales.dbf") // Result: .T.
? FILE("*.dbf") // Result: .T.
Files Library is CLIPPER.LIB.
