Identifiers are arbitrary names of any length given to functions, variables, symbol-

ic constants, user-defined data types, and labels. All these program elements will

be referred to as objects throughout the help (not to be confused with the meaning

of object in object-oriented programming).

Identifiers can contain the letters

a to z and A to Z, the underscore character “_”,

and the digits 0 to 9. The only restriction is that the first character must be a letter

or an underscore.

Case Sensitivity

mikroC identifiers are not case sensitive at present, so that Sum, sum, and suM rep-

resent an equivalent identifier. However, future versions of mikroC will offer the

option of activating/suspending case sensitivity. The only exceptions at present are

the reserved words

main and interrupt which must be written in lowercase.

Uniqueness and Scope

Although identifier names are arbitrary (within the rules stated), errors result if the

same name is used for more than one identifier within the same scope and sharing

the same name space. Duplicate names are legal for different name spaces regard-

less of scope rules. For more information on scope, refer to Scope and Visibility.
