If you
want to reference a file in only one place in a program so that you can easily
change it for another job or a later run, you can reference a filename indirectly.
Use a FILENAME statement, the FILENAME function, or an appropriate operating
system command to assign a fileref or nickname, to a
file.(footnote 1) Note that you can assign a fileref to a SAS catalog that is an external
file, or to an output device, as shown in the following table.
Referencing External Files Indirectly
External File Task |
Tool |
Example |
Assign a fileref to a file that contains input data. |
FILENAME |
filename mydata 'input-file';
|
Assign a fileref to a file for output data. |
FILENAME |
filename myreport 'output-file';
|
Assign a fileref to a file that contains program statements. |
FILENAME |
filename mypgm 'source-file';
|
Assign a fileref to an output device. |
FILENAME |
filename myprinter <device-type> <host-options>;
|
Specify the file that contains input data. |
INFILE |
data weight;
infile mydata;
input idno $ week1 week16;
loss=week1-week16;
|
Specify the file that the PUT statement writes to. |
FILE |
file myreport;
if loss ge 5 and loss le 9 then
put idno loss 'AWARD STATUS=3';
else if loss ge 10 and loss le 14 then
put idno loss 'AWARD STATUS=2';
else if loss ge 15 then
put idno loss 'AWARD STATUS=1';
run;
|
Bring statements or raw data from another file into
your SAS job and execute them. |
%INCLUDE |
%include mypgm;
