DATA statement

The tipper triangular part of the Huckel matrix for ethylene, Fq, (6-48), exclusive of the diagonal elements consists of only one element. It can be entered into Program QMOBAS by making the dimension of the matrix 2 and changing the data statement to enter 1 in the 1.2 position...

The Confidence Interval. The use of a confidence band around the data was of concern to the panel. Dr. Mitchell The confidence band is the first thing the analytical chemist should stick around the number he reports. That will not be a relative standard deviation or a linearity statement. The confidence band is the final output on data statements. It is something we should get in the habit of doing. The meaning of the band that I use is a band which encloses the true value with a certain probability, typically 90%. They are computations concerned only with precision. You would need, in addition, some sort of accuracy statement on that as necessary. The confidence band is typically symmetrical If the most likely concentration is 3 and the 90%... 

Though we solve here only the simple blending problem (1.29-1.30) by calling the module Mil, we present a main program which, apart from the specific input in its DATA statements, is rather general and performs a number of auxiliary operations. In particular, it reads the problem, calculates the dimensions, calls the module, locates and prints out the results. Later on we will solve other problems by this program, replacing only the data lines. 

The DATA statements contain the input data in the following order ... 

Hilbert matrices (and obviously their inverses) are positive definite and are frequently used for testing algebraic procedures (ref. 1). We present a main program, with the lower triangular of the inverse of in the DATA statements. 

The main program is now used with the DATA statements... 

We use the main program of Example 1.2 to solve the linear programming problem. At S =0 the constraints have the form (1.87). Thus the coefficients in each DATA statement are the molar absorption coefficients at the corresponding wavelength, whereas the right-hand side is the observed absorbance A.. The objective function coefficients are the sums in (1.89). 

You can easily reconstruct the data of (ref. 19) from the following DATA statements. 

The DATA statements of the following program include 12 data pairs... 

The program reads the dimension N, the number M of the vectors, and the array A(N,M) of coordinates in the canonical basis, all from DATA statements. The coordinates are read row-by-row, i.e., we specify the first coordinates in all vectors and proceed by coordinates. The program first prints the starting coordinates ... 

As noted in the preceding discussion of Sensitivity Data , TNT is comparatively insensitive and safe to handle. Consideration of the compilation of accident data (Ref 3) in Table 10 leads to the same conclusion. It is also noted that no one area is especially accident prone. The incident involving the expin of 10000 lbs is discussed in the section on Preparation portions of the plant were redesigned as a result. A Safety Data Statement (Ref 2) summarizes factors pertinent to its handling, shipping and use...

First, BASIC 7.0 includes a simple sprite editor. Just type SPRDEF, and a box appears on the screen. Enter which sprite you d like to define, then use the cursor keys and the number keys 1-4 to draw squares on the grid. When you re through, the sprite is stored into a reserved section of memory. This memory can be saved to disk with BSAVE, then recalled within your program with BLOAD, eliminating the need for DATA statements. 

One of those variables holds an illegal quantity of some kind. Type PRINT B to discover the value of B. If it s greater than 255 or less than 0, B is the culprit. When you POKE a number into memory, it has to be between 0 and 255. If B is 519, for example, the program will crash. In this case, the number is coming from a DATA statement. Maybe you left out a comma, or two lines got stuck together when you forgot to press RETURN after a line. Whatever the cause, you ll have to find the incorrect DATA statement. 

An adventure program consists of two parts the initialization and the main loop. The initialization section includes dimensioning arrays and setting up data. We ve already looked at some of the initialization section of our example adventure. It uses READ and DATA statements to set up all the initial values. Once the initialization is done, however, the main loop takes over. It runs until the game is completed. The overall flow of the main loop would be something similar to that shown in Figure 2. 

A sprite is defined by 63 binary numbers. The one bits (on) represent solid pixels. Zeros (off) represent blank areas, through which the screen background is visible. Normally, you sketch a sprite on a grid 24 squares across and 21 squares high. This is 3 bytes per row (8 bits 3 bytes = 24 bits) and 21 rows of bytes (3 21 = 63 bytes). But after you ve drawn the sprite, you have to convert the squares into binary, and then into decimal so that you can put the numbers in DATA statements. 

If you re a programmer, you re probably more interested in DATA statements. That way, you can use BASIC to READ and POKE the numbers into memory. If you have some kind of DATA maker, you can run it on the memory used by the sprite in Sprite Magic (again, the memory location is the sprite number times 64). But Sprite Magic has a special DATA maker of its own. It s similar to the Create DATA option in Ultrafont +, but it s been enhanced. 

Press CONTROL-D to create a series of DATA statements from the current sprite in memory. Just tap the key, or you ll get hundreds of DATA statements as the key repeats. Sprite Magic will create eight DATA statements, with eight bytes per line. The last byte is not strictly used. Sprite shapes are made... 

P j from 63 bytes, but the sprite areas are padded so that they ll conveniently fall in 64-byte ranges. To create DATA statements for another sprite, use the + or — key to move to the correct sprite page then press CONTROL-D again. 

A very useful command, CONTROL-D, allows you to create DATA statements for whatever characters you ve defined. Ultrafont + doesn t make DATA statements for all the characters, just the ones you ve changed. After you press CONTROL-D, Ultrafont 4- adds the DATA statements to the end of whatever program you have in BASIC memory. If there is no program, the DATA statements exist alone. 

You can load Ultrafont +, enter NEW to reset some BASIC pointers, load a program you re working on, then SYS 49152 to Ultrafont -t- to add DATA to the end of the program. The DATA statements always start at line 63000, so you may want to renumber them. If you press CONTROL-D twice, another set of DATA statements will be appended, also numbered from line numbers 63000 and up. Since the keys repeat if held down, just tap CONTROL-D. If you hold it down, you may find a hundred DATA statements have been created See the notes at the end of this article for more details on using DATA statements in your own programs. 

After you create the DATA, you ll still be in Ultrafont +. If you want to exit to see the DATA statements or go on to other things, press CONTROL-X. The screen will reset to the normal colors and you ll see the READY, prompt. If you ve made DATA, a LIST dramatically reveals it. It s best to enter the command CLR to make sure BASIC is initialized properly after creating DATA statements. One thing to watch out for Don t use RUN/STOP-RESTORE to exit Ultrafont +. The program moves screen memory from the default area at address 1024, and the RUN/STOP-RESTORE combination does not reset the operating system pointers to screen memory. If you do press it, you won t be able to see what you re typing. To fix it, blindly type POKE 648,4 or SYS 49152 to reenter Ultrafont + so you can exit properly. 

The DATA statements are created from lines 63000 and up, as many as necessary. Each line of data has nine numbers. The...
