Doesn't work - I just tried

TEXT TO lcProcedure NOSHOW
       PROCEDURE delCustomersTrigger
          INSERT INTO Customers_Tombstone(pk, dtDeleted) VALUES (CustomerPK, DATETIME())
       ENDPROC   
     ENDTEXT
     
     APPEND PROCEDURES FROM (STRTOFILE(lcProcedure,'temp.txt')) && Produced not a character expression.

BTW, I could not find how to add TABLE validation rule.
