View source for Inverted syntax

This page is the answer to the task [http://rosettacode.org/wiki/Inverted_syntax Inverted syntax] in the [http://www.rosettacode.org/wiki/Rosetta_Code Rosetta Code].

=== Description (from Rosetta Code) ===

{| class="wikitable" style="width:100%;"
| '''Inverted syntax with conditional expressions'''

In traditional syntax conditional expressions are usually shown before the action within a statement or code block:

<code> IF raining=true THEN needumbrella=true </code>

In inverted syntax, the action is listed before the conditional expression in the statement or code block:

<code> needumbrella=true IF raining=true </code>

'''Inverted syntax with assignment'''

In traditional syntax, assignments are usually expressed with the variable appearing before the expression:

<code> a = 6</code>

In inverted syntax, the expression appears before the variable:

<code> 6 = a</code>

'''Task'''

The task is to demonstrate support for inverted syntax forms within the language by showing both the traditional and inverted forms.

=== Answer ===

==== Inverted syntax with conditional expressions ====

The following is how is visualized the common [[Programming.If|If]] expression:

The following is the visualization of the [[Programming.InvertedIf|Inverted If]] expression. Note that they are different expressions, in order that they can be visualized in different form, but they reduce the same way.

==== Inverted syntax with assignment ====

The [[Symbolic.Assignment|Assignment]] expression does not have an inverted form, so it looks as usual;

However, Fōrmulæ supports right to left orientation, in such a case the last expression would look like:

<br clear=all>Right to left orientation might look confusing. The following are the right to left visualization of both the traditional and inverted conditional we have seen above:
