13.1 Searching for include files
---------------------------------
The compiler searches for a file includ in a program whose name is
defined by 'include' and in quotation marks as follows:
First it attempts to open the file in the current directory. If the
file is not there, it then attempts to open the file in the directory
indicated by #includepath. If this does not exist, or the file is not in
this directory, it attempts to open the file in the directory indicated by
the command-line switch /ip=path. If this was not specified or the file is
not in this directory, it attempts to open the file in the directory
indicated in c--.ini by the command ip=path. If the environment variable
was not specified or the file is not there, it makes one final attempt to
open the file in the directory from which the compiler was started.
If the name of the include file is in <> then the file is searched for
in the inverse order, except that the search is not done in the current
directory.
For the console version of the compiler, the names of the main module
and the include files can be more than 8 characters long.
