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. This error disappeared in the 2000 version of the software when it underwent a rewrite in C.PowerBASIC, formerly Turbo Basic, is the brand of several commercial compilers by PowerBASIC Inc. In the 1996 to 1999 versions of Accpac ERP for Windows, CA Realizer was responsible for the dreaded "CarlZ Error" which would periodically hang up the software. Increasingly uncompetitive, CA-Realizer was quietly retired from CA's product offerings in the late 1990s. Starting with version 4.0, MS Visual Basic continued to advance in functionality, leaving CA-Realizer behind. The final version was CA-Realizer 3.0, released around 1996. There were versions for 16-bit Windows 3.1, 32-bit Windows 95, and 32-bit IBM OS/2.

It offered some functionality (like a fairly useful spreadsheet) and cross-platform capability. Several versions were released, that provided a version of the BASIC programming language, a Rapid application development tool, including forms building and some powerful built-in components, that was comparable to, and competitive with Microsoft Visual Basic, in its early days.
