The OPTMODEL Procedure

Syntax: OPTMODEL Procedure

PROC OPTMODEL statements are divided into three categories: the PROC statement, the declaration statements, and the programming statements. The PROC statement invokes the procedure and sets initial option values. The declaration statements declare optimization model components. The programming statements are used to read and write data, invoke the solver, and print results. The statements are listed in the order in which they appear in the following text, with declaration statements first.

Note: Solver specific options are described in the individual chapters corresponding to the solvers.
