To expand on our previous example, let’s specify that the letter "C" be ignored:
40 A(NUM("C"))=1
100 A(256)=0
Now "ABC" will be equal to "AB" and "C" will be equal to "". You can see from line 100 that we have also specified a zero length special case table. As we add to our example, we will add to line 100. Because the array A(*) has been declared with a length of 257 characters, the array declaration in line 10 will also have to be changed as we add special cases.
