_CWD$ - mkilgore/QB64pe GitHub Wiki

The _CWD$ function returns the current working directory path as a string value without a trailing path separator.

workingDirectory$ = _CWD$

• 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.

• If an error occurs while obtaining the working directory from the operating system, error code 51 (Internal Error) will be generated.

Example: Get the current working directory, and move around the file system:

 '' ''
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"

We started at C:\QB64
We are now in C:\QB64\a_temporary_dir
And now we're back in C:\QB64
