This is an advanced calculator program written in C# that lets do simple operations with variables - some sort of an interpreted language. Parsing is done quite manually.
No support given. I haven't used this in ages myself (just use a Python interpreter for this nowadays)
Syntax:
command:
operation: ( ) ( )
numero: , .
Variable: a-z, A-Z
Decuimal: 0-9
VarOperator: '='
Operador: '+' '/' '-' '*'
