F$DIRECTORY is a lexical function that returns the current default directory name string. The F$DIRECTORY function has no arguments, but must be followed by parentheses.
Syntax
F$DIRECTORY()
Return_Value
A character string for the current default directory name, including brackets ([]). If you use the SET DEFAULT command and specify angle brackets (<>) in a directory specification, the F$DIRECTORY function returns angle brackets in the directory string.
Examples
$ SAVE_DIR = F$DIRECTORY() $ SET DEFAULT [CARLEN.TESTFILES] . . . $ SET DEFAULT 'SAVE_DIR'
This example shows an excerpt from a command procedure that uses the F$DIRECTORY function to save the current default directory setting. The assignment statement equates the symbol SAVE_DIR to the current directory. Then the SET DEFAULT command establishes a new default directory. Later, the symbol SAVE_DIR is used in the SET DEFAULT command that restores the original default directory.
Note that you can use the F$ENVIRONMENT() function with the DEFAULT keyword to return the default disk and directory. You should use the F$ENVIRONMENT function rather than the F$DIRECTORY function in situations involving more than one disk.
