[Coin-symphony] Problem reading integer variables from MPS

hello,

im reading my system from a MPS file, where all the
variables are integers and some are binaries. i tried
defining this in BOUNDS section of a MPS file, where i
put LO and UI bounds for integer variables and BV
bounds for binaries. This didnt work(no solution) so i
tried writing
MARK1      'MARKER'     'INTORG'
and
MARK2      'MARKER'     'INTEND'
at the beggining and end of the integer variables in
the COLUMNS section of a MPS file. Binary variables
are still defined in BOUNDS with BV. This did work,
but only on GLPK solver and not on SYMPHONY. Symphony
treats all the variables as binaries. What seems to be
the problem?

thanks
