Clever use for switch loop

[esmith]

While researching a solution for another thread, I came across a clever use of the switch statement. Often I wish I could set up cases that use conditionals rather than a specific value. In the past, I used multiple else/if statements, but now I can do this:

 

switch (true) {
   case counter<=8:
       table = "Table 1";
       break;
   case counter<=16:
       table = "Table 2";
       break;
   case counter<=24:
       table = "Table 3";
       break;
   case counter<=32:
       table = "Table 4";
       break;
   case counter<=40:
       table = "Table 5";
       break;
   case counter<=48:
       table = "Table 6";
       break;
   case counter<=56:
       table = "Table 7";
       break;
   case counter<=64:
       table = "Table 8";
       break;
   case counter<=72:
       table = "Table 9";
       break;
   case counter<=80:
       table = "Table 10";
       break;
   case counter<=88:
       table = "Table 11";
       break;
   case counter<=96:
       table = "Table 12";
       break;
   case counter<=104:
       table = "Table 13";
       break;
   default:
      table = "Table 14";
}

That is clever, but this works also:

table = "Table " + Int((counter - 1) / 8) + 1;

Touche. Perhaps my use case is a bad example. But testing for "TRUE" in a switch loop seems to open up several possibilities that may not always have a math one liner.

Yes, absolutely. I've used that before as well:

But, as that post shows, there's almost always a more succinct way to structure the code to isolate the actual comparisons.
