features such as history and tab-completion. To accomplish the latter, it relies heavily on the reflection support built into ROOT. User classes that follow these interfaces may also take advantage of these features. The language originally interpreted by CINT was actually something of a hybrid between C and C++, covering about 95% of ANSI C and 85% of C++. The syntax, however, is a bit more forgiving than either language. For example, the operator -> can be replaced by . with only an optional warning. In addition, statements on the command line do not need to end with a semi-colon, although this is necessary for statements in macros. As an alternative to CINT,
