I'm not took concerned about readability. I already code in the style of
spaghetti, so cleanliness is not my first concern. I think I might break
the switch into chunks of 20, and then use a single if statement to determine
which switch to compare the variable against.<br>
<br>
Thanks for the replies though.<br>
<br>
Bob, I know not of this 'C' you language speak of... unless you forgot to add
the '#' after it ;)<br>

<p class=MsoNormal>Well, if you write the code in C, just create an array of
addresses of arrays and just directly access the array by position. Then
you don't even need any comparisons. :-)<br>

I would agree that a switch statement would be the preferred method. <br>
Multiple nested if statements hurt code readability, let alone a 1-80 <br>
range.<br>
