Schema Script is a language for expression evaluation. It can perform all the standard arithmetic operators and can access schema objects (and their methods) as registered local and global variables.
Schema script is executed with a call to SchemaEvalRequest or SchemaScriptRun
Schema Script does not support flow control statements like if, do, while and function calls.
