Macro value is not resolved

Inp — Tue, 30 Dec 2014 18:20:20 GMT

Here is my simple coding.

DATA _NULL_;

START=TRIM(LEFT(SUBSTR(SYSPARM(),1,8)));

END=TRIM(LEFT(SUBSTR(SYSPARM(),10,8)));

START='MMDDYYYY';

END='MMDDYYYY';

IF START='MMDDYYYY' AND END='MMDDYYYY' THEN

DO;

PUT 'TEST1';

CURYEAR = YEAR(TODAY());

PREYEAR = CURYEAR -1 ;

CALL SYMPUT('CURYEAR',PUT(CURYEAR,4.));

CALL SYMPUT('PREYEAR',PUT(PREYEAR,4.));

END;

ELSE

DO;

PUT 'TEST2';

CALL SYMPUT('CURYEAR', SUBSTR(START,5));

CALL SYMPUT('PREYEAR', SUBSTR(END,5));

END;

%PUT &CURYEAR;

%PUT &PREYEAR;

Here is the part of the LOG, which says the &CURYEAR and &PREYEAR is not resloved. It is very strange , it didn't poped any error message. I need somebody's help.. I am using SAS 8.2 on the mainfram.

57 %PUT &CURYEAR;

WARNING: APPARENT SYMBOLIC REFERENCE CURYEAR NOT RESOLVED.

&CURYEAR

58 %PUT &PREYEAR;

WARNING: APPARENT SYMBOLIC REFERENCE PREYEAR NOT RESOLVED.

&PREYEAR

65 ENDSAS;

TEST1
