A command prompt (or just prompt) is a sequence of (one or more) characters used in a command-line interface to indicate readiness to accept commands. It literally prompts the user to take action. A prompt usually ends with one of the characters $ , % , # , [ 18 ] [ 19 ] : , > or - [ 20 ] and often includes other information, such as the path ...
In computer programming, a usage message or help message is a brief message displayed by a program that utilizes a command-line interface for execution. This message usually consists of the correct command line usage for the program and includes a list of the correct command-line arguments or options acceptable to said program.
POINT is an example of one of the many graphics commands included in the Zgrass language. POINT requires an X and Y location, as well as a color. In this example, the user supplied OFFSET moves the x position of the curve on the screen, while the Y position is supplied by the trig function, suitably enlarged for display (in this case, 80 times ...
For example, in DOS 5, if the current directory is C:\TEMP, then TRUENAME command.com will display C:\TEMP\COMMAND.COM (which does not exist), not C:\DOS\COMMAND.COM (which does and is in the PATH). This command displays the UNC pathnames of mapped network or local CD drives.
The following example shows how command-line completion works in Bash. Other command line shells may perform slightly differently. First we type the first three letters of our command: fir Then we press Tab ↹ and because the only command in our system that starts with "fir" is "firefox", it will be completed to: firefox
In computing, Pic is a domain-specific programming language by Brian Kernighan for specifying line diagrams. The language contains predefined basic linear objects: line, move, arrow, and spline, the planar objects box, circle, ellipse, arc, and definable composite elements. Objects are placed with respect to other objects or absolute coordinates.
OPTION – highlights Simons' BASIC keywords when using the LIST command; DELAY – varies the rate at which the LIST command scrolls the screen; FIND – searches the program for a string; TRACE – displays the line numbers as a program is running; RETRACE – displays results of a trace; DUMP – displays all variable values except for ...
This is also related to the syntax requirement that every line start with a command keyword, and pressing the one keypress for that command at the start of a line changes the editor from command mode to letter mode. Thus, variable assignment requires LET (i.e., LET a = 1 not only a = 1). This practice is also different from other BASIC dialects.
