11/6/2023 0 Comments Dosbox batch file more than 9![]() %0 through %9 are readily available, and any beyond %9 can be read by VERSION 1.0 | JASE T. In batch files they are read- only and are referred to by an escaped digit ('%' is the escape character in batch files). SYNTAX: EXAMPLE: Returns: %0 C:\MYPATH\MYFILE.BAT Yields: %0\.\NextFile.bat C:\MYPATH\NEXTFILE.BAT Command Line Variables Command line arguments are the strings following the program name in the command that invokes the program. With this variable, you can have your batch file dynamically determine it’s own location, and pass the path off to another script or look for other files within the same directory or sub-directories by using a special syntax: %0\.\ Using this notation, your script file can call another script file in the same or deeper location, without the environment needing to have the initial location in the PATH. This variable is useful because DOS batch files are not aware of where they are. This variable is accessed internally through %0, which returns the full path and name of itself.
