 Hi there,

 I had some trouble with the coin-mps-reader. To easily reproduce it, i run
 cbc on the
 following mps-file
 [[BR]]

 {{{
 NAME  mps problem
 ROWS
  N o
  E c1
  E c2
 COLUMNS
  x1 o 33.5 c1 1
  x1 c2 1
  x2 o 1.1 c1 1
 RHS
  m c1 1
  m c2 1
 BOUNDS
  BV bound x1 1
 ENDATA
 }}}


 which results in
 {{{
 ~/coin-Cbc/bin/cbc /tmp/m.mps
 Coin Cbc and Clp Solver version 1.01.00, build Jun 11 2007
 command line - cbc /tmp/m.mps
 At line 1 NAME  mps problem
 At line 2 ROWS
 At line 6 COLUMNS
 At line 10 RHS
 At line 13 BOUNDS
 No match for column 1 at line 14 <  BV bound x1 1 >
 At line 15 ENDATA
 Problem mps has 2 rows, 2 columns and 3 elements
  There were 1 errors when importing model from /tmp/m.mps
 There were 1 errors on input
 }}}


 Now I found one workaround, by replacing 'bound' in line 14 by 'bounds'.
 (oddly replacing it with 'bds1' works too.)
 [[BR]]

 Although, my file above might not fullfill the mps-fixed format; it looks
 reasonalbe
 wrt. the mps-free format.?
 [[BR]]
 Could it be, that the BV record is still read in some variant of fixed
 column format?
 [[BR]]
 best
 sven
