Just in time for the New Year, Microsoft Corp, Redmond, Washington began shipping the IBM and Microsoft OS/2 Software Development Kit for OS/2 version 2.0 with Presentation Manager on December 29 (CI No 1,334). OS/2 version 2.0 appears to be the name that has been settled on for what has variously been known as OS/3 and OS/2-386 – that is the first full 32-bit version of OS/2. The OS/2 Software Development Kit programme is intended to provide early software and tools to enable corporate and third-party developers to begin writing 32-bit applications for OS/2 version 2.0. Although the Kit is a joint product from IBM and Microsoft, the pre-release version is available only from Microsoft. OS/2 version 2.0 is scheduled for general release sometime this year – three years after OS/2 was launched and only after the 80386 has been superseded by the 80486. The Kit is intended to give impatient software developers a head start in the creation of full 32-bit OS/2 applications, something most of them have wanted since they first got to grips with OS/2. Microsoft promises that applications developed with the new kit will take full advantage of the 32-bit 80486 and 80386 architecture. It supports large, flat memory address space and demand paging, has a full suite of 32-bit application programming interfaces for development of larger programs and the ability to manipulate large data structures easily. It will also enable developers to transfer applications from other 32-bit systems, including Unix ones – although most of the traffic seems to be the other way these days. OS/2 2.0 is designed to run OS/2 1.0, 1.1 and 1.2 applications without modification and to run multiple MS-DOS and PC-DOS operating system applications at once, greatly improving MS-DOS support according to Microsoft. The Software Development Kit contains a pre-release version of OS/2 Standard Edition version 2.0 with Presentation Manager, a 32-bit compiler based on Microsoft C optimising compiler version 5.1, a 32-bit version of the Microsoft Macro Assembler version 5.1, Presentation Manager tools, sample code and On-Line support. But it’s clearly by no means the last word, and there may well be bugs in it Microsoft will periodically update the 2.0 SDK code and documentation through the final release of the product. Documentation includes Online Programming Reference and Guide; Application Design Guide; Systems Application Architecture Common User Access Advanced Interface Design Guide; Programming the OS/2 Presentation Manager; Advanced OS/2 Programming; Sample applications code. Presentation Manager Tools, comprise an Icon Editor; Dialog Box Editor; Font Editor. Debugging Support includes CodeView and Kernel Debugger. MS OnLine support until 90 days after general availability of the final SD 2.0 release. For the first pre-release version of the Kit, which doesn’t include Programming the OS/2 Presentation Manager, Advanced OS/2 Programming and Sample applications code – these follow later the developer will need an Intel 80386 or 80486-based machine with an exorbitant 6Mb of memory, EGA or VGA, and a 60MB hard disk. The Software Development Kit is $2,600 with a group discount offer of four copies for $8,500. Seasonal cheer is not in Microsoft’s heart: there is no upgrade pricing for people who bought previous versions of the OS/2 Software Development Kit.
