Examples: In AgentSheets or AgentCubes users can set games or simulations into a particular state in order to see how program would react. This level of support allows users to put artifacts created with a VPL into a certain state in order to explore how the program will react to that state.

Pragmatics: VPLs support the study of what programs mean in particular situations.This could include help functions providing documentation functions built-in to programming languages.

Semantics: VPLs may provide some mechanisms to disclose the meaning of programming primitives.

Syntax: VPLs use icons/blocks, forms and diagrams trying to reduce or even eliminate the potential of syntactic errors helping with the arrangement of programming primitives to create well-formed programs.

The general goal of VPLs is to make programming more accessible to novices and to support programmers at three different levels Visual programming environments provide graphical or iconic elements which can be manipulated by users in an interactive way according to some specific spatial grammar for program construction. VPLs may be further classified, according to the type and extent of visual expression used, into icon-based languages, form-based languages, and diagram languages.

For example, many VPLs (known as diagrammatic programming) are based on the idea of 'boxes and arrows', where boxes or other screen objects are treated as entities, connected by arrows, lines or arcs which represent relations. A VPL allows programming with visual expressions, spatial arrangements of text and graphic symbols, used either as elements of syntax or secondary notation. In computing, a visual programming language ( visual programming system, VPL, or, VPS) or block coding is a programming language that lets users create programs by manipulating program elements graphically rather than by specifying them textually.
