---------------------+------------------------------------------------------
GMPL model files without data section can exist. Unfortunately method
CoinMpsIO::readGMPL either wants a data section or a data file to be
given. Otherwise it terminates.
Data sections are not necessary in the following cases
- parameters are fully specified in the model section
- data is generated via random number generator
- data is read via the table IN statement from a file or a SQL data base
Please, check the appended patch file.
You can also have a look at the differences under the following URL
