Identifiers

InstallShield 2026 » InstallScript Language Reference

Identifiers are the names that you create to denote constants, variables, and functions in your script. Observe the following syntax rules when creating identifiers:

•

An identifier may be of any length, but only the first 63 characters are significant.

•

The first character of an identifier must be alphabetic (a-z, A-Z) or an underscore.

•

The remaining characters may be alphabetic (a-z, A-Z), numeric (0-9), or an underscore.

•

Each identifier must be unique. Be careful not to create an identifier that is a reserved word in InstallScript.
