Take Command was the name that JP Software used for their GUI command-line interpreters for Windows 3.1 (TC16), Windows 32-bit (TC32) and later OS/2 Presentation Manager (TCOS2). These were released concurrently with version 4DOS 5.5, 4NT 2.5 and 4OS2 2.52. The OS/2 and Windows 16-bit survived until version 2.02, they are still available for download from the FTP site on JP Software.
