You cannot and you shouldn't. It's a normal integer division overflow because the mathematical result is MAXLONGINT+1 which cannot be represented by a longint. Note that this error message occurs only in TP7.0 with a 386+, i.e. if the division is exectuted directly by a signed dword DIV. With TP 6.0 or TP7.0 with test8086:=0 you get instead the wrong result -2147483648 = longint($80000000). Regards Horst
