ExtTags Type (Enumeration)
estack.h

enum ExtTags {...};

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

If the tag of an entry on the expression stack is EXT_TAG (0xE3), then the byte below it is the extra TI-Basic function tag. ExtTags is enumerated type for describing such extended entries (see top_estack for more info about how entries on the expression stack are organized). This enum is quite big, and here is a complete list of extended function tags defined in it (all values are in hex), with their meaning (used notation is RPN):

Note: An empty list [] of optional arguments means the function does not take any optional arguments, but an END_TAG is needed nonetheless.

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