An Introduction to Byte Pie
In order to code in Byte Pie you must understand how memory addresses work. You must also learn about variables, objects, arrays and exceptions. This is a good starting point to begin learning about programming. Tech Tangents has a complete collection of Byte magazine they have put together on YouTube. Byte was a microcomputer magazine that was very influential in the 1970s and 1980s because of its wide-ranging editorial coverage. It was unlike other microcomputer magazines that focused on specific systems or home and business users.
In programming, variables are a way of organizing data. Variables are used to store and retrieve values, much like a file on your computer. There are a variety of different types of variables, and each has its own uses. In this chapter, you will explore the types of variables in Python, including integers, booleans, tuples, lists, and strings.
The amount of 1’s and 0’s in a binary number is called its length. A group of four bits is called a nibble, eight bits makes a byte, and so on. Adding a leading zero to the end of a binary value helps present this information more clearly.
Use a pie chart to display the relative size of different field values over an entire data set. To create a pie chart, you need a search that generates a single series. The search in this example searches for events related to a particular source field category and calculates the percentage share of each slice of the pie chart. The search also uses the transforming command to create a table.
A pie chart is a visualization that represents data as slices, with each slice representing a proportion of the whole. Each slice in a pie chart is generated from a single series of field values. Use a transforming search to generate this single series. For example, count events in each source field category and then transform the results to generate a single series for each slice of a pie chart.
Arrays are a powerful way to store a large amount of data of the same type. This helps you avoid the need to define numerous variables, which can become difficult to maintain as the program grows.
Using arrays, you can access the data in a very efficient manner. This is because they store the data in contiguous memory locations and each element has an index number.
The index number for the first element in an array is 0, and for every subsequent element, it increments by one. This allows the computer to efficiently access each value by referring to its index.
Arrays are useful for storing numeric values, boolean values (true and false), strings and objects. The most common use of arrays is in conjunction with loops. This is because it allows the computer to perform the same calculations on a large number of data items at once. This saves time and makes the program run faster. However, arrays present challenges when it comes to inserting and deleting data values as they have a fixed size and cannot be expanded.
Exceptions are used to terminate a program and take corrective action. When an exception occurs, control is returned to the exit routine which can alter the contents of general purpose registers 0 through 15 and the register save area for ESPIE or PIE. The procedure for altering these registers depends on whether the exception is a vector or scalar type. For vector types, your exit routine can check the two-byte interruption code (the first byte is the exception extension code) in the old program status word (OPSW in ESA/390 mode) to determine which type of exception was encountered.
Specify the size threshold, as a percentage of the whole pie, at which point slices collapse into one consolidated slice.
