Has this actually not funny matrix entry:

    x_63537   R0021476             1   R0021421            -1
    x_63538   R0021479             1   R0021425            -1
    C0063540  LB_full              0   $ empty column
RHS
    RHS1      LB_full            540   UB_full            540

nu4-pr9 and nu120-pr9

These ones...USE A TAB TO REPRESENT A FIXED NUMBER OF SPACES.

% grep '\t' /Users/oscar/Downloads/nu4-pr9.mps
 LI BOUND     C7309	0

function line_to_items(line)
items = split(line, " "; keepempty = false)
return String.(items)
end
