Copy the values of the control variables from one SLP problem to another

The following example creates a new problem and copies only the Xpress NonLinear controls from the existing problem (not the Optimizer library ones).

XSLPprob nProb;
XPRSprob xProb;
int Control;

XSLPcreateprob(&nProb, &xProb);

Control = 1<<1;
XSLPsetintcontrol(Prob, XSLP_CONTROL, Control);
XSLPcopycontrols(nProb, Prob);

Note that XSLP_CONTROL is set in the old problem, not the new one.

Normally XSLPcopycontrols copies both the Xpress NonLinear controls and the Optimizer Library controls for the underlying problem. If only the Xpress NonLinear controls are required, set the integer control variable XSLP_CONTROL appropriately.
