Row names and senses are defined in the ROWS section. Each row is declared on its own data line. Field 1 on a row data line contains one of the strings "G", "L", "E", or "N", to indicate the row's sense, according to the following table.

field 1 interpretation
G ≥
L ≤
E =
N no right-hand-side


An MPS-format file may define multiple "N" rows; the parser ignores each of them other than the objective row.
