Is there a way for this MPS file with specific format to be read and solved?
I am trying to use "readprob" with this MPS file. The error 770 appears. After changing the keyword XLINEAR by ROWS, it still cannot solve. Is there some way to solve the optimization problem by us...

Expanding a bit on Tristan's answer: your MPS file is nowhere near a file conforming to the MPS standard nor the extended MPS format used by Xpress.
I suggest to double-check the tool that creates this file and see whether it has an option to create a standard conformant file.
It is easy enough to shuffle and/or rename the sections in your file, but like Tristan said, the data inside the sections is in a bad format as well. For example, the XLINEAR section cannot be considered as ROWS sections since it not only specifies row sense and right-hand side, but also left-hand side coefficients.
