I hardly think so. As I understand it, Full_Name is meant to expand
simple file names like "file.txt" and relative file-names like
"../../foo/file.txt" into full names by using the default directory and
expanding "abbreviations" (A.16 (47)).
If the Command_Name is simply "bong.exe", you cannot expect Full_Name to
search through the file system to find the directory that contains
"bong.exe". There could be several such directories. Full_Name cannot
use the PATH envinroment variable to find the directory because PATH
only applies to executable files and Full_Name should apply to all files.
If Command_Name gives you only the simple name, and you want the full
name, I think you must use Ada.Environment_Variables to get the value of
PATH and then scan the PATH directories for the Command_Name. But then
it would be simpler to just put the "application path" into a well-named
environment variable and forget about Command_Name.
