SAS already puts your nose straight to where you made a mistake:

56 data cid;
57 set d.permanent;
58 cissd=intnx('month',couponexpiry,3);
59 c=format cissd date9.;

388

ERROR 388-185: Expecting an arithmetic operator.
 
ERROR 76-322: Syntax error, statement will be ignored.

c=format cissd date9.;

makes no sense.

You probably wanted

data cid;
set d.permanent;
cissd=intnx('month',couponexpiry,3);
format cissd date9.;
run;

Without the format you see the raw value of a SAS date, which is the number of days since 01jan1960.
