1 | visible length- or column value smaller than 1 |
2 | no change |
The virtual row length of all fields of a mask must be always identical and correspond to the record length. If fields are defined as multi-line fields (visible row length bigger > 1 < ), the virtual row length is calculated as the product of the visible row length and the number of records.
The dal_mas_siz_fld function automatically limits the total field length of all non-BLOB fields to 255 characters. So please use the dal_mas_set_typ_fld function to make sure the field type is known before trying to change the field dimension.
