Loops cannot be nested.
+<h3>Conditional Output</h3>
+
+The output of parsed lines can be suppressed:
+
+<pre>
+#IF:MYVAR < 66
+output if the value is smaller than 66
+#ELSE
+output otherwise
+#ENDIF
+</pre>
+
+A condition consists of exactly two values (both may be variables) and an operator. More complex expressions are not possible at the moment. If the condition evaluates to false, then the output and calculation of all lines until #ELSE or #ENDIF is suppressed.<p>
+
+At the moment the #ELSE statement reverses the output suppression between #IF and #ENDIF. Multiple #ELSEs are possible at the moment, but should not be relied upon in case the logic changes in subsequent versions.<p>
+
+Conditions cannot be nested, but conditions can be embedded in loops or be put around loops. If a condition is put around a loop, it does not prevent the processor from evaluating the loop, only the output and internal calculations are suppressed.<p>

<h3>Calculations</h3>
Numeric variables allow some very simple calculations in place:
More complex calculations can be done with the #CALC statement:
<pre>
-#CALC:TVAR/MONEY:@VAR1@ * @VAR2@ + 4
+#CALC:TVAR/MONEY:VAR1 * VAR2 + 4
</pre>
-The above creates the temporary variable "@#TVAR@" that is the product of @VAR1@ and @VAR2@'s content plus 4. It is marked as a monetary value.<p>
+The above creates the temporary variable "@#TVAR@" that is the product of @VAR1@ and @VAR2@'s content plus 4. It is marked as a monetary value. Please note that the variables are not enclosed in "@".<p>
Calculations are restricted to the operators below and are always done from left to right - more complex formulas require several lines. Tokens must be space separated. If no type or a non-existing type is requested INT is assumed. All calculations are done using 64bit signed integers. If the processor comes across an illegal token it sets the variable to "error".<p>
+Literals (above: "4") must be integers.<p>
