basop.h

The <basop.h> Header File

Routines for executing TI-Basic operators

Very few of the functions from this header file are documented as of now. Of course, the ones which are undocumented have not been tested, either. It is very likely that there are errors in this file, so use it with care.

However, we thought it might be a good idea to provide a header file for all of the built-in TI-Basic operators which have a documented entry in the jump table. This way, you can easily search for particular operators if you need them. If you use a function from this header file, please document it, too.

Many functions from this header file require their arguments to have some specific format. They usually have to be internally simplified, which can be achieved with the push_internal_simplify function from estack.h, and the result is an internally simplified expression as well.

If you do not want to accept the AMS dependency of these functions, you can usually construct an expression using their appropriate tags, and then call push_internal_simplify.

Predefined Types

CESI: Represents a pointer to a constant expression.
ESI: Represents an index of a value on the TIOS expression stack.
ESQ: Represents a quantum within an expression.
EStackIndex: Represents an index of a value on the TIOS expression stack.
Quantum: Represents a quantum within an expression.
SYM_STR: Represents a pointer to the terminating zero byte of a string.

Note: All functions from this header file get parameters from the expression stack, so this header file must be used in conjunction with estack.h. You need to learn about the usage of the expression stack before using any function from this header file. All functions defined here execute particular TI-Basic operators. They sometimes may be useful to perform some operations which can not be implemented in C easily. But note that if you use functions from this header file too much, this will decrease the performance of your program significantly. In an extreme case, it will in fact decrease to that of a TI-Basic program! So use functions from this header file only if it is really necessary. Also note that these functions act exactly like the appropriate TI-Basic commands (including throwing errors if something is wrong), so the use of an error tracking mechanism from the error.h header file is highly recommended.
