Hi Timo.
Thanks for your answer. Based on this I have implemented handling of this code using the constant XPRS_STOP_SOLVECOMPLETE.
I have found that the compiler flags this as an unknown constant in XPRESS 9.1 and so I will need to implement the constant's integer value instead.
A small complaint I have about XPRESS is that the numerical values of constants don't appear to be documented anywhere apart from the subset that can be looked up in XPRS.BAS.
