| #define INIT_COLS 10000 |
Read LP in MPS File Format.
The specification is taken from the IBM Optimization Library Guide and Reference, online available at http://www.software.ibm.com/sos/features/libuser.htm and from the ILOG CPLEX 7.0 Reference Manual, Appendix E, Page 531.
This routine should read all valid MPS format files. What it will not do, is find all cases where a file is ill formed. If this happens it may complain and read nothing or read "something".
