<Listing 2.9 in the Programmer's Guide To The Amiga gives you the
<path to where the binary is located.  You can use argv[0] for the
<binary's name.  The program is called mybranch.c

I must have not made myself clear - you're the second person to make
that mistake. The code in listing 2.9 prints the name of the current
directory. This is may not be the name of the directory that the
running file is from.  Consider the following script, with "myname.c"
as the program I'm looking for:

1> path
Current directory
bin:Utilities
bin:System
bin:S
C:
1> cd
src:c
1> cc myname.c -o myname
1> myname
src:c/myname
1> copy myname ram:
1> ram:myname
ram:myname
1> rename ram:myname c:		; Note: no longer a copy in current directory
1> myname
c:myname			; Or bin:c/myname, or dh0:c/myname, or etc.
1> rename c:myname c:system
1> myname
bin:system/myname		; Or dh0:system/myname, or some such.
1>

You see the difference? The code is conceptually simple, but has some
non-trivial details (like dealing with "//x/y/myname") to make it
work right.
