Environment
The Current Directory
The Current Directory
The most important environment for all tools is the current directory. The current
directory is the base search directory where the tool starts to search for files (for
example, for the DEFAULT.ENV / .hidefaults)
Normally, the current directory of a tool started is determined by the operation system
or by the program who launches another one (for example, WinEdit).
For the UNIX operating system, the directory in which, an executable is started is also
the current directory from where the binary file has been started.
For MS Windows based operating systems, the current directory definition is quite
complex:
If the tool is launched using a File Mana ger/Explorer, the current directory is the
location of the executable launched.
If the tool is launched using an Icon on the Desktop, the current directory is the
working directory specified and associated with the Icon.
If the tool is launched by dragging a fi le on the icon of the executable under
Windows 95 or Windows NT 4.0, the desktop is the current directory.
If the tool is launched by another launchi ng tool with its own working directory
specification (e.g. an editor as WinEdit), the current directory is the one specified
by the launching tool (e.g. working directory definition in WinEdit).
Changing the current project file does also change the current directory if the
other project file is in a different directory. Note that browsing for a prm file does
not change the current directory.
To overwrite this behavior, the environment variable DEFAULTDIR may be used.
The current directory is displayed among other information with the linker option “-v”
and in the about box.
Global Initialization File (MCUTOOLS.INI)
(PC only)
All tools may store some global data into the MCUTOOLS.INI. The tool first searches
for this file in the directory of the tool itself (path of the executable). If there is no
MCUTOOLS.INI file in this directory, the tool looks for a MCUTOOLS.INI file
located in the MS Windows installation directory (for example, C:\WINDOWS).
