Metadata Instruction: Perform a calculation with a non-numeric string or type cast a number into a string.
Edited By : Sobhit Sharma

• When inserting a string into a variable.
• When converting a number to string (i.e. type casting).
• For concatenating strings

CALCULATES evaluates non-numeric, numeric expressions and stores the output in another variable. The output of the command is going to be a String.

• DO NOT USE in the root node.
• Use variables only if they have been previously declared.

CALCULATES command is for node level operations. It can be used in any node as an instruction, except for the root node. It should not be used on the Arrows.

Let's take an example: CALCULATES $output_variable "My name is Joe Root"
Here, the value of the "$output_variable" is going to be "My name is Joe Root".
If you had a tree variable "$name" which was previously initialized to "Joe Root", the above command could also have been CALCULATES $output_variable "My name is $name"
