| coordinates | each of a group of numbers used to indicate the position of a point, line, or plane |
| code | the set of instructions forming a computer program which is executed by a computer |
| algorithm | a process or set of rules to be followed in calculations or other problem-solving operations, especially by a computer. |
| sprite | a computer graphic which may be moved on-screen and otherwise manipulated as a single entity. |
| random | made, done, happening, or chosen without method or conscious decision. |
| script | a program or sequence of instructions that is interpreted or carried out by another program rather than by the computer processor (as a compiled program is). |
| app | short for "application," which is the same thing as a software program. It may refer to a program for any hardware platform, it is most often used to describe programs for mobile devices, such as smartphones and tablets. |
| Block programming | a lexical structure of source code which is grouped together. They consist of one or more declarations and statements. |
| event | A block of code that senses something that triggers another set of code to run |
| input | Any information or data that is sent to a computer for processing |
| reporter | is a block that reports a value. These can be anything, from numbers to strings. |
| if-else | A high-level programming language statement that compares two or more sets of data and tests the results. If the results are true, the THEN instructions are taken; if not, the ELSE instructions are taken. |
| composition | is an act or mechanism to combine simple functions to build more complicated ones. |
| debugging | the routine process of locating and removing computer program bugs, errors or abnormalities, which is methodically handled by software programmers via debugging tools. |
| function | a named section of a program that performs a specific task and returns a value |
| procedure | a set of coded instructions that tell a computer how to run a program or calculation; performs some operation but does not return a value. |
| condition | features of a programming language, which perform different computations or actions depending on whether a programmer-specified boolean condition evaluates to true or false. |
| selection | Also called a decision, a question is asked, and depending on the answer, the program takes one of two courses of action, after which the program moves on to the next event. |
| sequencing | a structure where an action, or event, leads to the next ordered action in a predetermined order. It can contain any number of actions, but no actions can be skipped. |
| program | provide (a computer or other machine) with coded instructions for the automatic performance of a task |
| bug | an error, flaw, failure or fault in a computer program or system that causes it to produce an incorrect or unexpected result, or to behave in unintended ways |
