passing parm on footing when &RECORDS = 0

Hi guys,
How can I pass parm when data not exists in Hold file.
Here is what I have:
TABLE FILE TABLE1
PRINT COL1
WHERE USER_ID EQ 'USER1';
ON TABLE HOLD AS A1 FORMAT ALPHA
END
-RUN
-READ A1 &COL1.A20
END

-RUN
-SET &HLINK = IF &RECORDS NE 0 AND &COL1 NE '' THEN 'Drill-Down report with &COL1 view' ELSE '';

It works when &RECORDS NE 0 but when &RECORDS EQ 0, then I got the error message as:
(FOC295) A VALUE IS MISSING FOR: &COL1

Anyone knows how to solve this problem?


Thanks,

Default the variable you will read:

-DEFAULT &COUNTRY = '';

SET HOLDFORMAT=ALPHA
-RUN

TABLE FILE CAR
PRINT COUNTRY
WHERE COUNTRY EQ 'CANADA'
ON TABLE HOLD AS H001
END
-RUN

-READ H001 &COUNTRY.A10.

-TYPE COUNTRY: &COUNTRY

Francis,

I added
-DEFAULT &COL1= '';

Now I got error message as:
Unknown error occurred. Agent on reporting server EDASERVE may have crashed. Please investigate reporting server log.

You may do as Tom suggests or do this:

-DEFAULT &COUNTRY = '';
-DEFAULT &HLINK = '';

SET HOLDFORMAT=ALPHA
-RUN

TABLE FILE CAR
PRINT COUNTRY
WHERE COUNTRY EQ 'CANADA'
ON TABLE HOLD AS H001
END
-RUN

-READ H001 &COUNTRY.A10.

-RUN
-SET &HLINK = 
-  IF &RECORDS NE 0 AND '&COUNTRY' NE '' THEN 'FILE FOR: &COUNTRY' 
-  ELSE IF &RECORDS NE 0 AND '&COUNTRY' EQ '' THEN 'DONE'
-  ELSE '';

-RUN
TABLE FILE CAR
BY COUNTRY
ON TABLE FOOTING
"&HLINK.EVAL"
END
-EXIT


I added "ELSE ''" to the -SET statement.

As well, I don't think you need the .EVAL in the FOOTING.
