[Gretl-users] possible bug in cvs (and ods?)

Dear Gretl community: I have problems loading a database in cvs format. The error display "non-numercial value" when indeed its a numerical value. Could this be a bug, or just a problem of observation format or conversion? Also, I have a second question related to loading databases. When I try to load a dataset with strings in CVS I have no problem, but when I try to load the same dataset in ods or xls format I found the following error "Problem in column X: numerical value expected and found string". Why is there such different behaviour for the same database? If strings are possible in CVS why not in different format? Regards, Leandro
