GETPRO

     Search !PATH for a procedure, and copy into user's working directory

     Extract a procedure from an IDL Library or directory given in the
     !PATH  system variable and place it in the current default directory
     (presumably to be edited by the user).  GETPRO can also be used to
     obtain a copy of the default startup file.

     GETPRO, [ proc_name ]          ;Find PROC_NAME in !PATH and copy

     proc_name - Character string giving the name of the IDL procedure or
               function.  Do not give an extension.   If omitted,
               the program will prompt for PROC_NAME.

     None.

      A file with the extension .pro and a name given by PROC_NAME will
      be created on the user's directory.

      The system variable !PATH is parsed into individual libraries or
      directories.   Each library or directory is then searched for the
      procedure name.   When found, a SPAWN is used to extract or copy
      the procedure into the user's directory.    If not found in !PATH,
      then the ROUTINE_INFO() function is used to determine if it is an
      intrinsic IDL procedure.

       Put a copy of the USER library procedure CURVEFIT on the current
       directory
       IDL> getpro, 'CURVEFIT'

       User will be unable to obain source code for a native IDL function
       or procedure, or for a FORTRAN or C routine added with CALL_EXTERNAL.
       User must have write privilege to the current directory
       This procedure is not used with Macintosh IDL.
