{{DISPLAYTITLE:_CWD$}}
|
|
|
|
The [[_CWD$]] function returns the current working directory path as a string value without a trailing path separator.
|
|
|
|
|
|
{{PageSyntax}}
|
|
: {{Parameter|workingDirectory$}} = [[_CWD$]]
|
|
|
|
|
|
{{PageDescription}}
|
|
* By default, the initial working directory path is usually the same as the directory of the executable file run.
|
|
* The current working directory can be changed with the [[CHDIR]] or [[SHELL]] command; CHDIR sets it, _CWD$ returns it.
|
|
* Path returns will change only when the working path has changed. When in C:\ and run QB64\cwd.exe, it will still return C:\
|
|
* The current working directory string can be used in [[OPEN]] statements and [[SHELL]] commands that deal with files.
|
|
* Works in Windows, macOS and Linux. [[_OS$]] can be used by a program to predict the proper slash separations in different OS's.
|
|
|
|
|
|
{{PageErrors}}
|
|
* If an error occurs while obtaining the working directory from the operating system, [[ERROR Codes|error code]] 51 (Internal Error) will be generated.
