Raghu,

It's look okay to me...

only thing I'm sure about is the Format
in
-READ EXAMPLE &EXAMPLE.D20.2. NOCLOSE


From the help-files:
Is the format of the variable. For a free-format file, specifying this value is optional. For a fixed-format file, format is the length or the type and the length. The type is either A (alphanumeric), which is the default, or I (numeric). The format value must be delimited by periods. The format is ignored for comma-delimited files.

So only A and I are allowed... not D

Funny thing is we have a working procedure with this code:
-READ HOLD &CN2.A50


No period after the format.


hope it helps...
good luck
Dave

Hi Cyril,
Thanks for you reply
It is working for (.A20) but it is not working for D20.2.
We are using this variable for union 2 records if i use the varible,There we are facing problems because of the field format.

Thanks,
Raghu

As Dave said, only 'A' and 'I' formats are supported for -READ. In fact, there is no need to specify even the 'A' or 'I' because WebFOCUS will make its own determination as to whether the value is numeric or not when you try to use it. The period after the format is also not necessary.

In the example below, SALARY has a format of D12.2M in file EMPDATA. The value written to the SAVE file has a length of 12, including the decimals and decimal point. But a problem may occur when you try to use variable &SALARY in a calculation. If you do not set DMPRECISION, Dialogue Manager will perform the calculation and return only the integer portion of the result (decimals are truncated). You must set DMPRECISION in order to retain decimals in Dialogue Manager calculations.

TABLE FILE EMPDATA
 PRINT SALARY
 WHERE RECORDLIMIT EQ 1 ;
 ON TABLE SAVE
END
-*
-RUN
-READ SAVE &SALARY.12
-TYPE &SALARY
-*
SET DMPRECISION = 2
-RUN
-SET &TESTVAL = &SALARY / 2000 ;
-TYPE &TESTVAL

I am trying to figure out
1) why you are using HOLD instead of SAVE.
2) why you are using format TAB?

It will not work with an I because you are not reading an integer - it is a decimal. Try following Dan's example (just specify a length or even an A12 would work.) The DMPRECISION setting is what will allow it to be used as a floating decimal.
I would also suggest skipping the TAB format. ON TABLE HOLD FORMAT ALPHA or ON TABLE SAVE will get you what you need.

Darin

Raghu,
One more reason for the error. "I"-integer can hold a maximum of 11 digits. When you say error in the code, please post the error message too.

TABLE FILE CAR
SUM
DEALER_COST
ON TABLE HOLD AS TAB123 FORMAT TAB
END
-RUN

?FF TAB123
-READ TAB123 &DCOST.I11.
-TYPE &DCOST


Hope this helps.
