INFORMIX-SQL 7.3 Perform Screens:

According to documentation, in an "after editadd editupdate of table" control block, its instructions are executed before the row is added or updated to the table, whereas in an "after add update of table" control block, its instructions are executed after the row has been added or updated to the table, supposedly meaning that any instructions which would alter values of field-tags linked to table.columns would not be committed to the table, but field-tags linked to displayonly fields will change?.. However, when using "after add update of table" I placed instructions which alter values for field-tags linked to table.columns and their displayed and committed values also changed!.. I would have thought that an "after add update of table" would only alter displayonly fields.
