Variables
==========

GeoArmadillo uses the Blockly features to define variables.
After clicking on *create variable...* in the variables section of the toolbox,
Blockly creates a set of *Blocks* for accessing the variable.

This is the example output of creating the variable *my model*.

Currently, GeoArmadillo only uses the lowermost *Variable Block*, which can be joined into other blocks.

Paths
=======

To enter a file path in the file system, please use the *File Path Block*. The path can be absolute or relative:
