The following program is an example of the ALGOL-like BASIC dialect that Turbo Basic supported. The integrated development environment could run a BASIC program internally for traditional BASIC debugging (see sample below), or generate an MS-DOS stand-alone executable file that could be run on other systems without the Turbo Basic product or runtime libraries. Other implementations were either interpreters, or relied heavily on a runtime library. Unlike most BASIC implementations of its time, Turbo Basic was a full compiler which generated native code for MS-DOS. PBDOS creates 16-bit DOS MZ executable files, while PBWIN and PBCC create 32-bit Portable Executable (PE) files.īorland's Turbo Basic contains extensions to classic BASIC (without breaking compatibility), such as a drawing API and mouse access. In all versions of the compiler, the applications compile without external libraries, though it can use such libraries if needed. PowerBASIC programs are self-contained and use no runtime file to execute. PowerBASIC Tools LLC still sells new licenses for the 32-bit Windows compilers. No corrections (such as adding the correct DPI settings for the IDE) have been released. No development activity has been reported. No 64-bit version or beta release has been announced. No new version has been released since v10.03 (11 years ago as of May 2022). However, development of PowerBASIC products has stopped. When Bob Zale died, PBWin11 and PBCC7 were in beta testing, and 64-bit compilers and PB/Pro (PBWin and CC in one compiler) were in the alpha stages. This was later confirmed by Vivian Zale with a forum post thanking the members for their support. On January 31, 2017, Adam Drake announced Drake Software had acquired the PowerBASIC source code from PowerBASIC, Inc., with the intention of updating and improving the functionality of the product. On November 2, 2016, Vivian Zale announced her intention to seek a buyer for the company. On May 10, 2015, Vivian Zale announced that work was continuing on new versions of PowerBASIC compilers. His wife, Vivian Zale, posted on 8 March 2014 to the PowerBASIC forums a statement that the company would continue in operation. For a time, it was assumed that the company might cease operations. On November 6, 2012, Robert Zale, the creator of PowerBASIC, died. PowerBASIC went on to develop BASIC compilers for Windows, first PBWIN - their flagship product - and then PBCC, described below. to continue support and development of it it was later called PBDOS. ![]() When Borland decided to stop publishing it (1989), Zale bought it back from them, renamed it PowerBASIC and set up PowerBASIC Inc. Turbo Basic was originally created by Robert "Bob" Zale (1945–2012) and bought from him by Borland. Later it was extended to MS-DOS/PC DOS and in 1987 Borland distributed it as Turbo Basic. The first version of the DOS compiler was published as BASIC/Z, the very first interactive compiler for CP/M and MDOS. The Windows versions use a BASIC syntax expanded to include many Windows functions, and the statements can be combined with calls to the Windows API. The MS-DOS version has a syntax similar to that of QBasic and QuickBASIC. ![]() There are both MS-DOS and Windows versions, and two kinds of the latter: Console and Windows. that compile a dialect of the BASIC programming language. PowerBASIC, formerly Turbo Basic, is the brand of several commercial compilers by PowerBASIC Inc. ![]()
