PowerBASIC is the brand of several commercial compilers by Venice, Florida-based PowerBASIC Inc. that compile a dialect of the BASIC programming language with a syntax similar to that of QBasic and QuickBASIC. The first version was published as BASIC/Z; later it was distributed by Borland as Turbo Basic and since 1989, it has been known as PowerBASIC.[1][2][3] A diagram of the operation of a typical multi-language, multi-target compiler. ... Venice is a city in Sarasota County, Florida, United States. ... This article is about the programming language. ...

Characteristics

PowerBASIC is a native-code BASIC compiler, unlike some other versions of BASIC which are interpreted, and is faster than many other implementations.[4] Unlike some other versions of BASIC, such as Visual Basic, PowerBASIC programs are self-contained and do not require runtime files to execute. In computer science, an interpreter is a computer program that executes, or performs, instructions written in a computer programming language. ... This article is about the Visual Basic language shipping with Microsoft Visual Studio 6. ...


The PowerBASIC for Windows compiler can create both GUI-based EXEs and DLLs, while PowerBASIC Console Compiler for Windows can create command line applications. Both Windows versions include an IDE with source debugger, and offer access to independent DLLs if desired. PowerBASIC Forms, a visual user interface design tool, is also available as an add-on for PowerBASIC for Windows.[5] This article or section does not adequately cite its references or sources. ...

The PowerBASIC for Windows compilers are compatible with the Windows 9x series and the Windows NT series of operating systems, including Windows Vista and Windows Server 2008.[6] PowerBASIC for DOS is also available including support for versions of DOS from 3.30 onwards and includes a DOS-based IDE.[7] Windows 9x is the family of Microsoft Windows operating systems that comprises the 32-bit, DOS-based Windows versions: Windows 95, Windows 98, and often also Windows Me. ... Windows NT (New Technology) is a family of operating systems produced by Microsoft, the first version of which was released in July 1993. ...

Windows Server 2008 is the name of the next server operating system from Microsoft. ... This article is about the family of closely related operating systems for the IBM PC compatible platform. ...


Notable language features of 32-bit compilers

  • Array functions to SORT, SCAN, INSERT, DELETE, and ASSIGN
  • DDT (dynamic dialog tools) to create GUI interfaces
  • COM (component object model) client functions
  • Communications: COM ports, UDP, TCP, EMAIL
  • Dynamic pointers which don't require a pointer variable
  • Extended precision floating point calculation (80-bit/18 digit)
  • Graphics with optional auto-scaling
  • Inline assembler, including SIMD opcodes
  • MACRO engine with multi-line and function macros
  • MAT (matrix) functions
  • Menu statements for dynamically creating and modifying menus
  • Pointers with multiple levels of indirection
  • Printing to host-based ("Windows-only") printers
  • Regular expressions with search/replace
  • Run-Time libraries and DLLs are not required
  • Threads with thread-safe support code
  • User-defined types and unions

Syntax

Some of the syntax differs from other languages for statements dealing with arrays, dialogs and controls. Many of these are multi-word statements. For example, to get a result from scanning an array for a value, the syntax is:

 Array Scan a(), = 23, To i 

Where the variable "i" receives the result. In some other languages, this might be implemented as a function, for example:

 i = ArrayScan(a(), 23) 

"Hello World" program

This example program displays a messagebox saying "Hello World"

 #Compile Exe "Hello.exe" Function PBMain MsgBox "Hello World" End Function
