![]() In the personal computer operating systems MS-DOS and PC DOS, a number of standard system commands were provided for common tasks such as listing files on a disk or moving files. Some commands were built-in to the command interpreter, others existed as transient commands loaded into memory when required. Though they may seem complicated, one nice property of complex behaviors is that they are always composed of smaller behaviors. Over the several generations of MS-DOS, commands were added for the additional functions of the operating system. Complex Behaviors Example: Follow a defined path through an entire maze These are behaviors at the highest levels, such as navigating an entire maze. ![]() Debugger Displays There are several different debugger windows that can be used when the ROBOTC debugger is operational. ![]() In the current Microsoft Windows operating system a text-mode command prompt window can still be used. One of the commands is Set Next Instruction which allows you to change the currently executing point of your program to this selected line The pop-up menu is shown in the picture below. Some DOS commands carry out functions equivalent to those in a UNIX system but always with differences in details of the function. The command interpreter for MS-DOS runs when no application programs are running. When an application exits, if the command interpreter in memory was overwritten, MS-DOS will re-load it from disk. The command interpreter is usually stored in a file called "COMMAND.COM". Command robot -version So, we can see Robot Framework 3.0.4 is installed. It is a direct client of the Robot service, and communication is done through a WCF channel. Command pip install robotframework Once the installation is done, you can check the version of robot framework installed as shown below. The Robot Command Line Interface (UiRobot.exe) is a console application which can request to start jobs, and waits for their output. Some commands are internal and built-into COMMAND.COM, others are stored on disk in the same way as application programs. We will now use pip python package manager to install the robot framework and the command for it is as follows. ![]() When the user types a line of text at the operating system command prompt, COMMAND.COM will parse the line, and attempt to match a command name to a built-in command or to the name of an executable program file or batch file on disk. If no match is found, an error message is printed and the command prompt is refreshed. ![]()
