tool to write batch filesAny text editor or word processor with ASCII output  Batch file extensions - .BAT or .CMD Execute the batch file the same ways as you do any commandCh 10 24Writing and Executing a Writing and Executing a Batch File to Save KeystrokesBatch File to Save KeystrokesBatch files can save keystrokes.Examples: DIR/AD DIR/OS and DIR/O-SCh 10 25Sometimes easier to use COPY CON instead of EDIT to write simple batch file.Syntax:COPY CON filenameWriting and Executing a Writing and Executing a Batch File to Save KeystrokesBatch File to Save KeystrokesCh 10 26Drawbacks to using COPY CON:Cannot correct errors once <Enter> is pressed Cannot correct errors in existing files Writing and Executing a Writing and Executing a Batch File to Save KeystrokesBatch File to Save KeystrokesCh 10 27To correct errors need text editor like EDIT.Nothing is faster than COPY CON.Writing and Executing a Writing and Executing a Batch File to Save KeystrokesBatch File to Save KeystrokesCh 10 28KEY CONCEPTS:Pressing <F6> and <Enter> signals completion<Ctrl> +Z same as pressing <F6>Displaying file with TYPE indicates it is ASCII file Create one-line batch files Directories
