Nothing, that's what you are meant to have!!! AmigaOS will automatically
know that any calls to PROGDIR:filename really means <programs
path>:filename.
e.g.
void main()
{
long handle = NULL;
if( handle = Open( 'PROGDIR:testfile.txt', MODE_NEWFILE ) )
{
Close( handle );
handle = NULL;
}
}
If you run this, you find an empty file called testfile.txt in which ever
directory the program ran from. Of course this might vary for CLI launched
programs as the OS might use the current directory rather than the
directory the program resides in, I can't remember.
But it definitely works from WB, I know I use it all the time :-)
Kind regards...
Alex
