Thanks Francis Mariani.

But i do not want TABLE FILE for this requirement.

I want to store previous 3 month name in webfocus variables and use that variables in my report.

Convert to Smart Date to feed into DATEADD.
Convert to Alphanumeric to feed into CHGDAT.
Look over Date and Time Functions in the Help file to get a better understanding of what was done.
  
-SET  &LAST_3MONTH = CHGDAT('YYMD','MX', DATECVT(DATEADD(DATECVT(&YYMD, 'I8YYMD', 'YYMD'), 'M', -3), 'YYMD', 'A8YYMD'), 'A17');
-TYPE &LAST_3MONTH
-EXIT

Or you could use the legacy function AYM to subtract 3 months from the current month:

-SET &CURR_MTH = EDIT(&DATEYYM,'9999$99');
-SET &MTH3_AGO = AYM(&CURR_MTH,-3,'I6YYM');
-SET &MTH_NAME = LCWORD(3,CHGDAT('A6YYM','MT',&MTH3_AGO,'A3'),'A3');
-TYPE &DATEYYM &MTH3_AGO &MTH_NAME

Thank you very much Mighty Max and Dan Satchell for such a small code.

I was done this using below code

  
-SET &DT1  = DATECVT(DATEADD(DATECVT (&YYMD,   'I8YYMD', 'YYMD'),'M', -1 ), 'YYMD','I8YYMD');
-SET &M1 = EDIT(&DT1,'$$$$99$$') ;
-SET &DT2  = DATECVT(DATEADD(DATECVT (&YYMD,   'I8YYMD', 'YYMD'),'M', -2 ), 'YYMD','I8YYMD');
-SET &M2 = EDIT(&DT2,'$$$$99$$') ;
-SET &DT3  = DATECVT(DATEADD(DATECVT (&YYMD,   'I8YYMD', 'YYMD'),'M', -3 ), 'YYMD','I8YYMD');
-SET &M3 = EDIT(&DT3,'$$$$99$$') ;
-TYPE &M1 &M2 &M3;
-SET &MM1 =  IF &M1 EQ 01 THEN 'Jan' ELSE IF &M1 EQ 02 THEN 'Feb' ELSE IF &M1 EQ 03 THEN 'Mar' ELSE IF &M1 EQ 04 THEN 'Apr' ELSE IF &M1 EQ 05 THEN 'May' ELSE IF &M1 EQ 06 THEN 'Jun' ELSE IF &M1 EQ 07 THEN 'Jul' ELSE IF &M1 EQ 08 THEN 'Aug' ELSE IF &M1 EQ 09 THEN 'Sep' ELSE IF &M1 EQ 10 THEN 'Oct' ELSE IF &M1 EQ 11 THEN 'Nov' ELSE 'Dec';
-TYPE &MM1;
-SET &MM2 =  IF &M2 EQ 01 THEN 'Jan' ELSE IF &M2 EQ 02 THEN 'Feb' ELSE IF &M2 EQ 03 THEN 'Mar' ELSE IF &M2 EQ 04 THEN 'Apr' ELSE IF &M2 EQ 05 THEN 'May' ELSE IF &M2 EQ 06 THEN 'Jun' ELSE IF &M2 EQ 07 THEN 'Jul' ELSE IF &M2 EQ 08 THEN 'Aug' ELSE IF &M2 EQ 09 THEN 'Sep' ELSE IF &M2 EQ 10 THEN 'Oct' ELSE IF &M2 EQ 11 THEN 'Nov' ELSE 'Dec';
-TYPE &MM2;
-SET &MM3 =  IF &M3 EQ 01 THEN 'Jan' ELSE IF &M3 EQ 02 THEN 'Feb' ELSE IF &M3 EQ 03 THEN 'Mar' ELSE IF &M3 EQ 04 THEN 'Apr' ELSE IF &M3 EQ 05 THEN 'May' ELSE IF &M3 EQ 06 THEN 'Jun' ELSE IF &M3 EQ 07 THEN 'Jul' ELSE IF &M3 EQ 08 THEN 'Aug' ELSE IF &M3 EQ 09 THEN 'Sep' ELSE IF &M3 EQ 10 THEN 'Oct' ELSE IF &M3 EQ 11 THEN 'Nov' ELSE 'Dec';
-TYPE &MM3;

That if statement can be much easier and shorter.

Look at the function DECODE
-SET &MM1= DECODE &M1(1 jan 2 feb 3 mar 4 apr) etc...

Even better... you don't even need to move the date 1, 2 or 3 months back.

Just 'jinx' the decodes.

-SET &M = EDIT(&YYMD,'$$$$99$$');
-SET &M_MIN1 = DECODE &M( '01' 'DEC' '02' 'JAN' '03' 'FEB' '04' 'MRC' '05' 'APR' '06' 'MAY' '07' 'JUN' '08' 'JUL' '09' 'AUG' '10' 'SEP' '11' 'OCT' '12' 'NOV'); 
-SET &M_MIN2 = DECODE &M( '02' 'DEC' '03' 'JAN' '04' 'FEB' '05' 'MRC' '06' 'APR' '07' 'MAY' '08' 'JUN' '09' 'JUL' '10' 'AUG' '11' 'SEP' '12' 'OCT' '01' 'NOV'); 
-SET &M_MIN3 = DECODE &M( '03' 'DEC' '04' 'JAN' '05' 'FEB' '06' 'MRC' '07' 'APR' '08' 'MAY' '09' 'JUN' '10' 'JUL' '11' 'AUG' '12' 'SEP' '01' 'OCT' '02' 'NOV'); 

-TYPE &M_MIN1
-TYPE &M_MIN2
-TYPE &M_MIN3
