While IBM and Apple were making their pitch for the desktop yesterday, Dick Pick was in London previewing Pick Systems Inc’s own bid to rule the desktop with Advanced Pick for MS-DOS, AP-DOS, a new single-user, multi-tasking virtual memory implementation of the Pick operating system integrated with MS-DOS so that where the R83 release needs its own partition and takes over the machine when installed, AP-DOS goes into an existing MS-DOS partition, seamlessly integrating Pick and MS-DOS applications – they can be invoked from Pick Basic, which can call C, Fortran, Pascal and assembler subroutines. Users can access and update MS-DOS files or convert them for use by Pick. The new implementation includes enhancements to the file system and better security, and is available within days in the UK at an introductory price of UKP100, which will rise to something like UKP300.
