Further information
XSLPreadprob tries to open the file with an extension of "mat" or, failing that, an extension of "mps". If both fail, the file name will be tried with no extension.
XSLPreadprob is capable to read most Ampl .nl files. To specify that a .nl file is to be read, provide the full filename including the .nl extension.
For details of the format of the file, see the section on Extended MPS file format.
