Description

A 16 bit Ada compiler targeting DOS and OS/2 1.x and later ported to 32 bit OS/2 2.x and higher and 32 bit extended DOS using VCPI, because the VCPI version had been validated the company was unwilling to bear the cost of validating a DPMI version and thus the 32 bit code output by the DOS compiler will not work in OS/2 or Windows.

Thomson

Alsys was taken over by Thomson in the mid 90's, they sold the OS/2 version for a while but dropped it fairly quickly and soon thereafter sold the Ada product line to German safety critical software specialist Aonix, who in turn merged with British embedded specialist Artisan Software to form Atego, who themselves were taken over by PTC more recently.

Versions

  • Accounts differ on what was the last OS/2 version, a large number of version 5.5 are out there branded Alsys, but some claim that a bug fixed version 5.6 existed as well that was branded Thomson.
