-- Command: aslrequest ID/K, TITLE/K, ATTRS/K/M
     This command will bring up a standard ASL file requester.  Note
     that this command is syncronous.  That is once it is issued it
     will not return a result until the user has selected a
     file/directory or canceled.  Once a file/directory has been
     selected then the fully path-qualified name will be returned in
     the `ARexx' variable RESULT (assuming `options results' was
     specified in the script).

        * ID - this argument specifies a window ID.  If specified then
          the requester will be associated with the window.

        * TITLE - this argument specifies the requester title (placed
          in the title bar of the requester window).

        * ATTRS [ISG] - with this option any ASL attribute TAGs may be
          set (refer to AmigaDOS RKMs for details).

     Some useful TAGs for use with this command are:

          TAG_Name =                        TAG_id
