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"

Remember that variable names are case-sensitive

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"
