PRINT
options ;
The PRINT statement is useful for displaying part of a solution summary, examining intermediate tableaus, performing sensitivity
analysis, and using parametric programming. In the options, the colnames
and rownames
lists can be empty, in which case the LP procedure displays tables with all columns or rows, or both. If a column name or
a row name has spaces or other special characters in it, the name must be enclosed in single or double quotes when it appears
in the argument.
The options that can be used with this statement are as follows.
displays a Solution, Variable, and Constraint Summary for the best integer solution found.
displays a Variable Summary containing the logical and structural variables listed in the colnames
list. If the / SENSITIVITY option is included, then sensitivity analysis is performed on the price coefficients for the listed
colnames
structural variables.
displays a Variable Summary containing only the integer variables.
displays a Variable Summary containing only the integer variables with nonzero activity.
displays a Variable Summary containing only the integer variables with zero activity.
displays the submatrix of the matrix of constraint coefficients defined by the rownames
and colnames
lists. If the / PICTURE option is included, then the formatted submatrix is displayed. The format used is summarized in Table 6.2.

displays a Variable Summary containing only the continuous variables.
displays a Variable Summary containing only the continuous variables with nonzero activity.
displays a Variable Summary containing only the variables with nonzero activity.
displays the results of parametric programming for the current value of the PRICEPHI= option, the price coefficients, and all of the price change vectors.
displays the results of parametric programming for the current value of the RHSPHI= option, the righthandside coefficients, and all of the righthandside change vectors.
displays a constraint summary containing the rows listed in the rowname list. If the / SENSITIVITY option is included, then
sensitivity analysis is performed on the righthandside coefficients for the listed rownames
.
displays the Solution Summary, including the Variable Summary and the Constraint Summary.
displays a Variable Summary containing only the variables with zero activity. This may be useful in the analysis of ON/OFF, ZERO/ONE, scheduling, and assignment applications.
