As gellyfish correctly states, substr() is being used as an lvalue here, i.e. something you can assign to. In this case, you are replacing five characters (the third argument) of $DATE, starting at position two (the second argument, and counting from 0) with the concatenation $YEAR.$MONTH. Hence the output you observe. CU
