The [_CWD$](_CWD$) function returns the current working directory path as a string value without a trailing path separator.
|
|
|
|
## Syntax
|
|
|
|
> workingDirectory$ = [_CWD$](_CWD$)
|
|
|
|
## Description
|
|
|
|
* 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](CHDIR) or [SHELL](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](OPEN) statements and [SHELL](SHELL) commands that deal with files.
|
|
* Works in Windows, macOS and Linux. [_OS$](_OS$) can be used by a program to predict the proper slash separations in different OS's.
|
|
|
|
## Error(s)
|
|
|
|
* If an error occurs while obtaining the working directory from the operating system, [ERROR Codes](ERROR-Codes) 51 (Internal Error) will be generated.
|
|
|
|
## Example(s)
|
|
|
|
Get the current working directory, and move around the file system:
|
|
|
|
```vb
|
|
|
|
startdir$ = _CWD$
|
|
PRINT "We started at "; startdir$
|
|
MKDIR "a_temporary_dir"
|
|
CHDIR "a_temporary_dir"
|
|
PRINT "We are now in "; _CWD$
|
|
CHDIR startdir$
|
|
PRINT "And now we're back in "; _CWD$
|
|
RMDIR "a_temporary_dir"
|
|
|
|
```
|
|
|
|
```text
|
|
|
|
We started at C:\QB64
|
|
We are now in C:\QB64\a_temporary_dir
|
|
And now we're back in C:\QB64
|
|
|
|
```
