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.

The patch file description is wrong. It should be "Patch to allow models w/o data section"
