[Clp] NEOS Question

[William H. Patton]

The columns are a bit wrong, The N,L should be in column 2.
Also in the columns section the Name0,1,Value1 fields start 1 col late;
Name2, Value2 seem OK so their headings are wrong.  Try this
NAME          Prob1
ROWS
 N  z
 L  r1
 L  r2
 L  r3
COLUMNS
    x1        z         5              r1        2
    x1        r2        4              r3        3
*
    x2        z         4              r1        3
    x2        r2        1              r3        4
*
    x3        z         3              r1        2
    x3        r2        2              r3        2
RHS
    b         r1        5
    b         r2        11
    b         r3        8
ENDATA

Hello,

I keep getting the same error message, and I can't find the error in my MPS
format. Perhaps the body of my message gets shifted when I send it...

Below is the problem that I have sent in. --Thanks, Alisher

Several minutes later, the "results" arrived. However, as you can see from
the message below, the results came back with an error.
