LINCON Statement
LINCON linear_constraint-1 <...,linear_constraint-n> ;
LINEAR linear_constraint-1 <...,linear_constraint-n> ;
where linear_constraint has the form

linear_expression- type linear_expression-

where linear_expression has the form

<+|->linear_term-1 <..., (+|-) linear_term-n>

where linear_term has the form

(variable | number<* variable>)

The keyword type can be one of the following:

<, <=, =, >=, >, <>, LT, LE, EQ, GE, GT, NE

The LINCON statement allows for a very general specification of linear constraints. In particular, it allows for specification of the following types of equality or inequality constraints:

     

For example, the constraint can be expressed as

var x1 x2;
lincon 4 * x1 - 3 * x2 = 5;

and the constraints

     

can be expressed as

var x1 x2;
lincon 10 <= 10 * x1 - x2,
       x1 + 5 * x2 <> 15;

Note that variables can be specified on either side of an equality or inequality in a LINCON statement. Linear constraints can also be specified by using the CONDATA= data set.

Regardless of the specification, you must define the variables by using a VARIABLE statement or implicitly by specifying the USECONDATAVARS= option.

User-specified scalar values are subject to rounding based upon a platform-dependent tolerance.
