Wrong result with ATODBL function

Hi,

I'm trying to convert an alphanumeric variable to a double precision format variable with the ATODBL function but there is a problem: I always become 0.00000 as result.

TABLE FILE OPP020
PRINT 
     O20TXUNITE
     O20ACOURS1
COMPUTE CHANGE/D14.7 = ATODBL('&MYVAR.EVAL','14',CHANGE);
END


THE &MYVAR variable is the result of this:

-READ TABDEVPF &MYVAR.14


In the master file, MYVAR is P14.7

Thanks for your help,

Jérémy.

Which isn't alpha which is what ATODBL is supposed to have as input. It returns zero if it doesn't like the input.

-SET &ECHO=ALL;
-SET &MYVAR = 2912.12234;

TABLE FILE CAR
PRINT 
COMPUTE CHANGE/D14.7 = ATODBL('&MYVAR','&MYVAR.LENGTH',CHANGE);
COUNTRY
END


The length (second parameter for ATODBL) must be exactly the length of the data in the variable - the best way to to do this is to use &var_name.LENGTH.

&vars are not classified as alpha or numeric. If the value contains 100 you could use it in either expression below without having to change any formats.

WHERE CODE EQ '&var';

OR

WHERE COUNTER GE &var;

The exception would be for dates. If it contains a value which will be compared as or used in further DATE computations, it needs to be converted to a smart date.

The use of quote marks tells the expression whether it is to be used as alpha or numeric.

You should just be able to say
COMPUTE CHANGE/D14.7=&MYVAR ;

Darin

Why didn't I think of that?

Thanks Leah and Francis,

I replaced '14' by '&CHGDEVREF.LENGHTH' but it's always the same result : 0,0000000.

I think the problem is that the input format is alpha (' 0,6318400') and not 0,6318400 like your sample.

Another idea?

And so what can I do? If I try this:

  
TABLE FILE OPP020
PRINT 
     O20TXUNITE
     O20ACOURS1
COMPUTE CHANGE/D14.7 = ATODBL(&MYVAR,'14',CHANGE);
END


There is this error:

(FOC275) FOCUS FUNCTION HAS INCORRECT NUMBER OF ARGUMENTS;
(FOC009) INCOMPLETE REQUEST STATEMENT BYPASSING TO END OF COMMAND

What I was saying is that there is no need to use the ATODBL function.

COMPUTE CHANGE/D14.7=&MYVAR ;
And it appears that you need to make sure the CDN setting is correct (ON)

I think you will have to change the "," to a "." - I don't think functions or DEFINE/COMPUTE can handle "," as the decimal separator.

SET CDN = ON/OFF/SPACE/QUOTE only works for displaying data in a report.

Not quite sure how this worked for the other side of the pond.
