As the other areas grow, they push into the Free RAM area making it smaller. As the other areas shrink, the Free RAM area gets larger. Page Operator Stack Hardware Stack. The Hardware Stack should not be used for saving large amounts of data.
Using the Hardware Stack to save register values upon entry to routines should not cause problems. TI Plus Developer Guide Page Fig. Certificate List Area This area contains a list of unit certificates for the specific calculator. A list of entry point equated labels is provided in the file, TI83plus. The IY register is set to the start of this flag area and does not change, resulting in easy bit manipulation. Page Table 2. Page 26 Used by applications to provide easy bit flag implementation.
Once an application completes, flag will most likely be changed by another application. It will not hold its state. Because they are floating-point numbers these variables are all nine bytes. Because these variables are always needed, the system always keeps them around and never changes their addresses. These variables are created by both users and the TI Plus system. The following sections contain an overall description of TI Plus variable naming conventions, data structures, creation, and accessing.
Page Real Data Type Structure A floating-point number has a left-justified mantissa the most significant digit is always the first digit. A floating-point number has a digit mantissa and an exponent range of to Page Complex List Data Type Structure 00 80 60 00 00 00 00 00 00 A row or column dimension cannot be 0, and it cannot be greater than If an application creates a matrix with either of these illegal dimensions, the TI Plus system may lock up.
Table 2. The first token of the name is tVarMat, which labels it as a matrix variable name. The second token signifies which predefined matrix name it is, [A] — [J]. The second token signifies which predefined picture name it is, tPic1 — tPic0. Listed below are the naming rules that these variables have in common. The restriction on the length of the name varies by data type and is detailed for each data type.
Page User-Named Lists Program names can be up to eight tokens in length. If less than eight tokens, the name must be zero 0 terminated. Like program names, these variables do not have leading tokens to signify that they are AppVar names. The sign byte of AppVar names must be set correctly. The remaining bits are random and must be masked off to get the correct data type when checking. This is important information since variables that are archived need to be unarchived for use by nearly all system routines and also for easier direct access by applications.
Page Creating Variables Do not create variables with sizes outside of their specified limits. For example, do not create a list with elements. The system does not check for these types of errors when creating a variable. Page 47 Chapter 2: TI Plus Specific Information Some system routines will fail and may cause a lock-up condition if bad data is input to them.
For more information see the Variable Data Structure section earlier in this chapter. Page Storing To Variables The current contents of the variable are not deleted if the new data being stored to the variable does not fit in memory.
Page Recalling Variables Chapter 2: TI Plus Specific Information Error checking is done to make sure that the data type being stored to the variable is valid for that variable. If the variable being stored to is archived, a system error is generated. Page Deleting Variables The graph equations should not be deleted without immediately recreating them. The TI Plus system will crash if these equations are not created. If an application wants to free the RAM used by a graph equation, it can delete the equation and immediately recreate the equation with a size of 0 bytes.
Error if the variable is archived. This routine checks the contents of DelVar the b register to be non-zero. If the contents is non-zero, it assumes the variable is archived and generates a system error.
They can also be unarchived - removed from the archive area and placed into RAM. System errors can be generated. See the Error Handlers section for further information. First is to fill the 16 byte cache with mode data from the archive, whenever it has been completely read. Second, is to return the next byte from the cache to the caller. See the System Routine Documentation for details. Following are the two routines, with examples, used to increase the data size and to decrease the data size.
The Symbol Table begins in high memory at the end of the hardware stack and grows towards low memory backwards.
Variable Value Operating the TI VARS and then the name of the variable or function. When you press a key or key combination to display a menu, one Menu or more menu names appear on the top line of the screen. The menu name on the left side of the top line is highlighted. Page 46 Selecting an Item You can select an item from a menu in either of two ways. Note: On the menus, only items you can select them by pressing the appropriate number key.
Page Vars And Vars Y. EOS lets you enter numbers and functions in a simple, straightforward sequence. EOS evaluates the functions in an expression in this order: Within a priority level, EOS evaluates functions from left to right. Page 49 To enter a negative number, use the negation key. Functions in the first level, such as squaring, are evaluated before negation.
If you select the home screen is displayed. Read the chapter for details. Suppose you want to model flipping a fair coin 10 times. You want to track how many of those 10 coin flips result in heads. You want to perform this simulation 40 times. If you use two lists in the Math Operations same expression, they must be the same length. Page 54 ] is stored as a constant on the TI You can use numbers, expressions, lists, and matrices. If the answer cannot be simplified or the resulting denominator is more than three digits, the decimal equivalent is returned.

Enter an initial guess for the variable for which you are solving. This is optional, but it may help find the solution more quickly. Also, for equations with multiple roots, the TI will attempt to display the solution that is closest to your guess. The default guess is calculated as Math, Angle, and Test Operations , follow these steps.

Page Entering And Using Complex Numbers To select a complex-number mode, press z, and then select either of the two modes.
Also, complex numbers are valid list elements. Real unless you entered a complex number as input. Page 67 Interpreting Complex numbers in results, including list elements, are displayed in either rectangular or polar form, as specified Complex Results by the mode setting or by a display conversion instruction page 2.
In the example below, are set. Rectangular- Rectangular-complex mode recognizes and displays a complex number in the form Complex Mode component, Page 69 angle angle of complex numbers, calculated as tan the imaginary part and a is the real part. With each random-number sequence for a given seed value. The TI factory-set seed value for random-number sequence, store any nonzero seed value to. To restore the factory-set seed value, store rand or reset the defaults Chapter Page 71 nPr, permutations of items taken number at a time.
Both items and number can be lists. Page 72 randInt randInt integer within a range specified by lower and upper integer bounds. If the angle mode is not set to the TI can interpret the argument as degrees, minutes, and seconds. Page 74 radians designates an angle or list of angles as radians, Radians regardless of the current angle mode setting.
The mode setting must be answer to be interpreted as degrees, minutes, and seconds. The TI performs. The TI performs On the TI, you can define one function in terms of another. Chapters 4, 5, and 6 describe aspects that are unique to parametric graphing, polar graphing, and sequence graphing. The TI has four graphing modes. Func Other mode settings affect graphing results. Chapter 1 describes each mode setting.
