Empty integer field - Error Message (WebFOCUS 4.3.5)

Hi there,

I have a little problem with a report. If I use the following lines
COMPUTE DAYSDIFF/I6 = IF DATE2 NE '' THEN DMY(DATE1, DATE2) ELSE '';
I get an error message, because "''" is not integer. How am I supposed to do thant? As I want to work on with the result I need to have the field empty under above condition.

Many thanks in advance
Christopher

Chris, this code is trying to set an integer variable to an alpha value. its trying to give an I6 field a value of blank. that'll cause an error every time!

Chris,

You could do it with:

COMPUTE DAYSDIFF/I6 = DMY(DATE1, DATE2);

COMPUTE DAYSA/A6 = IF DATE2 NE '' THEN EDIT(DAYSDIFF) ELSE '';

or you could:

COMPUTE DAYSDIFF/I6S = DMY(DATE1, DATE2);

if all you need is to print a blank.

kidpete,

thanks for the tips you provided. The problem with the first solution is that there are leading zeros with the EDIT statement. The second way ist not possible because there are zeros I want to display (when the two dates are identical).

Anyone with another idea?

Thanks a lot
Christopher

Ok, this worked for me. I had to change the field to an alpha, so it that won't work for you then this may not help.


COMPUTE DIFF/D12 = IF DATE1 EQ DATE2 THEN 0 ELSE DATE2 - DATE1;

COMPUTE DIFF2/A12 = IF DIFF GE 0 THEN FTOA(DIFF, '(D12)', DIFF1) ELSE '';

Good Luck!

Does the calculation have to be done in a compute, or could you use a define? If you used a define you could do:

DAYSDIFF/I6 MISSING ON= IF DATE2 NE '' THEN DMY(DATE1, DATE2) ELSE MISSING;

Regards
