Re: How to find directory where the program is?

[Philippe Waroquiers <wao@gull.sup.cfmu.eurocontrol.be>]

If you are using GNAT, in GNAT.OS_Lib, you find:
   function Locate_Exec_On_Path
     (Exec_Name : String)
      return      String_Access;
   --  Try to locate an executable whose name is given by Exec_Name in the
   --  directories listed in the environment Path. If the Exec_Name doesn't
   --  have the executable suffix, it will be appended before the search.
   --  Otherwise works like Locate_Regular_File below.
   --
   --  Note that this function allocates some memory for the returned value.
   --  This memory needs to be deallocated after use.

This could be used (you need to find the command name first) to find
the executable file
