Dear Pedro.
I think you can convert the field to ## (instead of a single #). This is because the sign "-" requires space when considering the length of a field. Otherwise the structure of the datafile would break and no longer work.
The other way around should work as well although it seems like a lot of work for introducing a negative number.
Kind Regards, Torsten Bonde Christiansen.

Dear EpiData friends,
I have a qes like this
days NUMBER OF DAYS WITHOUT MEDICINE IN THE PERIOD ##
However the ones who filled the CRFs filled this with -1 if there was no information about this question.
Now Im testin the entrys to start feeding the datasets and just realize that -1 is not a legal integer for field #
I thought that converting this field from # to <A > would work and later in the analysis to encode this variable to integer.
WOuld this work? any more elegant workaround?
Best regards,
Abraço forte e que a força esteja com você, Pedro Emmanuel _______________________________________________ EpiData-list mailing list EpiData-list@lists.umanitoba.ca http://lists.umanitoba.ca/mailman/listinfo/epidata-list
