String reverser breakdown

This sample reverses the string "Reversed" and prints it out.
Here you can find the color scheme used. Without it, obtained via the -standardize command (plus some manual recolor), it would look like this:

Which can be decompacted into:

Line by line explanation:

1. "Reversed" is saved into a variable .

2. An empty string (final output) is saved into another variable . The black pixel is a non-displayed character that forces a string initialization.

3. A for-each is used on our string which is read character by character.

4. A lambda.open opens the sub-block and takes an argument (the character of the string which is being read).

5. The output variable gets updated: its new value is: current char + output value .
   Again, the black pixel is used to force string concatenation between the values.

6. lambda.close closes the for-each block.

7. Print is called on the output value . desreveR is the output.
