Naming rules for variables and functions

Description

Names of variables and functions must begin with a letter or one of the following special characters: % _ # ! ? $. Next characters may be letters, digits, or any special character among _ # ! $ ?.

Upper and lower case letters are different.

Multilingual UTF-8 characters are accepted. Names may be as long as you want.

_ is reserved to ignore an output argument assignment.

Examples

// Valid names
%eps
A1 = 123
#Color = 8
þæ_Ð = %pi

// Non valid names
//1A , b%, .C

// Long names
The_name_of_an_identifier_is_not_length_limited = 1

// A kilometric name:
name = strcat(part("a",ones(1,1000))); // 1000-char long
execstr(name+"=%pi; b ="+name);
b
