-====== How do I interpret the Column Listing? ====== 
-Q: //I get in my lst file:// 
-X(1,1) (.LO, .L, .UP = 0, 0.0033, +INF) 
-1           ​equation_X(1,​1) 
-(-147.9179) Calc_Y(1,1) 
-//The Variable X is used in calc_y. What does each value correspond to ?// 
-Submitted by Arne Drud: The line: ''​X(1,​1) (.LO, .L, .UP = 0, 0.0033, +INF)''​ tells you which variable you are looking at and what its bounds and current value are. 
-The next line:''​1 ​          ​equation_X(1,​1)''​ tells you that the variable above appear in equation ''​euation_X(1,​1)''​ 
-and the the coefficient is 1, and that the relationship is linear. If the relationship is nonlinear there will be a parenthesis around the coefficient as shown next. 
-The third line: ''​(-147.9179) Calc_Y(1,​1)''​ tells you that the same variable appear in equation ''​Calc_Y(1,​1)'',​ 
-that the derivative in the current point (X(1,1) = 0.0033 from above is -147.9179, and the parenthesis says that the derivative is nonlinear so it could be different in another point.
