Codewise

A theme may be, in itself, perfectly moral, but if the plot is replete with offensive and unacceptable details, the entire story becomes unacceptable codewise.

The four symbols are designated 1, 2, 3 and 4 and their codes are 0001, 0111, 1101 and 1100, respectively, as shown on the map in Fig. 4. Note that only symbols 3 and 4 are codewise adjacent.

So what is really happening codewise? During runtime, the interpreter attempts to execute all the code within the try statement.
