Tags

Type (Enumeration)

enum Tags {...};

An enumeration to describe types of entries on the expression stack.

This enum is very large, as there are a lot of various entries. See top_estack for more info about how entries on the expression stack are organized. Here is a complete list of tags with their values in hexadecimal notation, along with their meaning written in RPN:

Note: For compatibility with TI's compiler, their tag names are also supported.
