Hi Manoj, If your non-compliant C++ code worked on a C++ compiler that happened to be lax (i.e., allowed non-compliance), as I see it your two choices are: + continue to use the lax C++ compiler + make your non-compliant C++ code C++ compliant My expectation is that the non-compliant C++ code which is brought into compliance should still work on the older compiler without issue. Sincerely, --Eljay
