why it keeps saying "QtrNum has been defined as both character and numeric", hash object definition

[ZRick]

data difference (drop=goalamount)/**/;

    length goalamount 8 ;

    if _n_=1 then    do;

        declare hash goal();

            goal.definekey('QtrNum');

            goal.definedata("goalamount");

            goal.definedone();

            /*avoid the NOTE of "var uninitialized "*/

            call missing(qtrnum,goalamount);

          goal.add(key:'qtr1', data:10);

            goal.add(key:'qtr1', data:15);

            goal.add(key:'qtr3', data:5);

            goal.add(key:'qtr4', data:15);

    end;

    set sasuser.contrib;

    goal.find();

    Diff=amount-goalamount;

run;

Define a hash object, log keeps saying

"

ERROR: Variable QtrNum has been defined as both character and numeric.

"

I don't get where I cause the error? I checked Listserv, but still don't know how to fix this.

This example is from advanced sas certification, chapter 17, hash object definition, hard-code section, this is a buggy code, just doesn't work.

Did you define the type of QtrNum before defining Hash Table?

data difference (drop=goalamount)/**/;

    length goalamount 8 ;

    if _n_=1 then    do;

    length QtrNum $ 8;

        declare hash goal();

            goal.definekey('QtrNum');

            goal.definedata("goalamount");

            goal.definedone();

            /*avoid the NOTE of "var uninitialized "*/

            call missing(qtrnum,goalamount);

          goal.add(key:'qtr1', data:10);

            goal.add(key:'qtr1', data:15);

            goal.add(key:'qtr3', data:5);

            goal.add(key:'qtr4', data:15);

    end;

    set sasuser.contrib;

    goal.find();

    Diff=amount-goalamount;

run;

It still didn't work, now it says:

ERROR: Duplicate key.

ERROR: Key not found.

ERROR: Key not found.

ERROR: Key not found.

ERROR: Key not found.

ERROR: Key not found.

ERROR: Key not found.

OK. you need add a return code before Hash methods.

         rc=goal.add(key:'qtr1', data:10);

           rc=goal.add(key:'qtr1', data:15);

            rc=goal.add(key:'qtr3', data:5);

            rc=goal.add(key:'qtr4', data:15);

           rc=goal.find();

I got the same problem, and I believe there is an typo on the book"SAS Certification Prep Guide-Advanced Programming for sas 9", page 606.

the code:     "length goalamount 8;" should be changed to: "length qtrnum $8  goalamount 8;"

I submitted the following program, and it runs with no error:

data diffe (drop=goalamount);
length goalamount 8 qtrnum $4;
if _N_=1 then do;
declare hash goal();
goal.definekey("qtrnum");
goal.definedata("Goalamount");
goal.definedone();
call missing(qtrnum, goalamount);
goal.add(key:'qtr1',data:10);
goal.add(key:'qtr2',data:15);
goal.add(key:'qtr3',data:5);
goal.add(key:'qtr4',data:15);
end;

set tian.contrib;
rc=goal.find();
diff=amount-goalamount;
run;
