Variables Name
A variable can have a short name (like x and y) or a more descriptive name (age, carname, total_volume). Rules for ChardScript variables:
A variable name must start with a letter or the underscore character
A variable name cannot start with a number
A variable name can only contain alpha-numeric characters and underscores (A-z, 0-9, and _ )
Variable names are case-sensitive (age, Age and AGE are three different variables)
Example
Legal variable names:
call myvar = "John"
call my_var = "John"
call _my_var = "John"
call myVar = "John"
call MYVAR = "John"
call myvar2 = "John"
Illegal variable names:
call 2myvar = "John"
call my-var = "John"
call my var = "John"
Multi Words Variable Names
Variable names with more than one word can be difficult to read.
There are several techniques you can use to make them more readable:
Camel Case
Each word, except the first, starts with a capital letter:
call myVariableName = "John"
Pascal Case
Each word starts with a capital letter:
call MyVariableName = "John"
Snake Case
Each word is separated by an underscore character:
call my_variable_name = "John"
