NULL values when printing report

When i print a report from table sdtsui (described below), null values are inserted (after the desc_suivi field) and some lines are too long. In the output section, i put report to "test.out". When i open this file with vi, it tells me that there are 2 nulls. When i open it with textedit, i can see the strange ^@ character 2 times. It seems that ^@ is converted with many spaces when being print. Any hints ? Thanx. here is the structure of the table: create table sdtsui ( no_demande integer not null , date_suivi date not null , no_suivi serial not null , desc_suivi char(260), { informix SQL 7.24 is buggy with char fieldsover 250-300 char ... } date_cree date, date_maj date ); -- Daniel Racine Analyste-programmeur Ville de Sherbrooke
