InstructionTags

Type (Enumeration)

enum InstructionTags {...};

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

If the tag of an entry on the expression stack is EXT_INSTR_TAG (0xE4), then the byte below it is the tag of a TI-Basic command token. Although TI-Basic tokens are not interesting for programming, they are defined in enumerated type InstructionTags, due to completeness. This enum is quite big, and here is a complete list of TI-Basic instruction token tags defined in it (all values are in hex), with their meaning (used notation is RPN):

Note: Displacements for jumps are 2 byte quantities in little endian format. Displacements in front of loop ending instructions are towards the beginning of the loop.

Note: An empty list [] of optional arguments means the instruction 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.
