Reading Field Symbol that is an internal table

Hello fellow ABAPers,

     Here is my current source code abbreviated..

data: ausp_itab(50) value '(SAPLCLFM)ALLAUSP[]

field-symbols: <fs_ausp>  type any,

                    <wa_ausp> type any.

assign (ausp_itab) to <fs_ausp>.

After this I cannot syntactically get a READ or a LOOP to work to extract this data in the field symbol.

The system thinks the <fs_ausp> is a DB table and gives the error on the read statement, when you try the LOOP the system says that it isn't an internal table. 

Not quiet sure what to do here!  Any help would be appreciated, thanks.
