system.directory
Syntax
- sret = system.directory(<s><,scustom>)
Set and retrieve the current system directory.
If the function is called with no arguments, returns the current system directory.
If called with one argument, the function first looks for a keyword match with the following special cases:
- input
- Set the current directory to be the same as the currently processing data file (if any).
- engine
- Set the current directory to be the same and the directory of the main engine module (dll).
- executable
- Set the current directory to the location of the executable file for the code.
- project
- Set the current directory to the location of the current project file (if any).
- custom
- Set the current directory to the contents of the second string provided in scustom.
If s does not match any of the above options, it is assumed to be a new directory name and is processed immediately.
If not successful, an error will occur.
The return value is the absolute path of the current directory before the change.
Returns: sret - the current directory before processing the function.
Arguments: s - String specifying which directory to use
scustom - Specific directory to use when the custom option is chosen in the first argument.
