Use the FILEREF function to verify that the fileref MYFILE is associated with an external file, and then use PATHNAME to retrieve the name of the external file:
rc=fileref('myfile'); if (rc=0) then do; fname=pathname('myfile'); put "Path = " fname; end;
This example assigns the fileref F1 to
/u/sasssf
, and then uses
F1 in a second call to FILENAME. The second call to FILENAME defines the fileref
F2 by appending
/temp
to
the path for F1.
rc=filename('f1','/u/sasssf'); path=pathname('f1'); put path=; rc=filename('f2','temp',",",'f1'); path=pathname('f2'); put path=;
The output would be
path=/u/sasccf path=/u/sasccf/temp
In this example, FILENAME concatenates the directories
/u/sasccf
and
/u/sasshh
and assigns the concatenated list of names to the fileref
F1. The second call to FILENAME is the same as the second call to FILENAME
in Example 2. However, in this example, because F1 is assigned to a concatenated
list of directory names instead of to a single directory, FILENAME does not
append
/temp
to the paths.
rc=filename('f1',"'/u/sasccf','/u/sasshh'"); path=pathname('f1'); put path=; rc=filename('f2','temp',",",'f1'); path=pathname('f2'); put path=;
The output would be
path=('/u/sasccf','/u/sasshh') path=('/u/sasccf','/u/sasshh')
