Use "IF" and "ELSE" verbs for conditional command blocks; ending the last block with a dot.

   IF Condition
      Statement block ...

   ELSE IF Condition
      Statement block ...

   ELSE
      Statement block ...
   .

For case statments compare an Expression to a list of constants using the same format as conditional comparison lists. The Expression can be either an integer or enumerated type.

   IF Expression is Value | Value | ...
      Statement block ...

   ELSE IS Value | Value | ...
      Statement block ...

   ELSE
      Statement block ...
   .

Note that with nested blocks the final dots may be placed on the same line as in this example:

   IF Name = "ALPHA"
      Alpha += 1

   ELSE IF Name = "BETA"
      Beta += 1

   ELSE
      Unknown += 1

      IF Unknown is 1 to 10 | 20 | 30
         Low += 1

      ELSE
         Limit = Unknown
   .  .
