As its a dynamic array, I would use SetLength on it, before assigning to its elements. The array is already initialized with the initialization directly following its declaration. A SetLength() is not necessary in that case.

OK, but its initialised to 4x4. 0..4 is 5 I think. Cheers, Peter _______________________________________________ fpc-pascal maillist - [email protected] https://lists.freepascal.org/cgi-bin/mailman/listinfo/fpc-pascal
