<br><font size=2 face="sans-serif">Kyle,</font>
<br>
<br><font size=2 face="sans-serif">The asserts have been modified to give
an error message (bad format of input image). The reason was that
on output values of > 1.0e40 are output as blank. This was a cheap
fix for bounds but should not apply to elements or objective. The large
values should now be output approximately correctly - as Senator Everett
Dirkson said - 1.0e40 here and 1.0e40 there and soon you are talking real
money!</font>

<br><font size=2><tt>In addition to the problems mentioned below, trying

mpsfile from the same experiment, I ran clp (the test program in the <br>
clp directory), and got the following assertion.<br>
<br>
CoinMpsIO.cpp:669: failed assertion `after>next'<br>
<br>
Any thoughts as to what problems might cause this sort of behavior? <br>
I'm sure it's my own fault, I'm just trying to narrow down the causes.<br>
