Purpose
Interrupt the optimizer algorithms.
Synopsis
procedure stopoptimize(why:integer)
Argument
why 
The reason for stopping. Possible reasons:

Time limit hit
XPRS_STOP_CTRLC 
Control C hit
XPRS_STOP_NODELIMIT 
Node limit hit

Solution limit hit
XPRS_STOP_USER 
User interrupt
XPRS_STOP_GENERICERROR 
Some unspecified error
XPRS_STOP_MEMORYERROR 
Out of memory
XPRS_STOP_SOLVECOMPLETE 
The solve is complete

The license was lost
XPRS_STOP_NUMERICALERRO 
A numerical error has occurred
XPRS_STOP_WORKLIMIT 
Work limit hit
XPRS_STOP_NEXTOBJECTIVE 
Stop the current solve, but continue with solving the next objective
