Improper equation ".." statements - error I

Each declared equation must be specified with a statement, which contains certain elements.  Omitting the ".." causes error $36.  Omitting the equation type ("=L=", "=E=", or "=G=") causes error $37.  Omitting the specification of a declared equation is marked with messages $71 and $256.  The example shorterr11.gms illustrates the first two such errors under the use of the errmsg=1 option which repositions the error message explanatory text.
