            a symbol table for a symbol name
         
         (tblsearch table-name symbol [setnext]) 
 
         Arguments
         
- table-name
 
            - 
               
                  A string that identifies
                     the symbol table to be searched. This argument is not case-sensitive.
                  
                
             - symbol
 
            - 
               
                  A string identifying
                     the symbol name to be searched for. This argument is not case-sensitive.
                  
                
             - setnext
 
            - 
               
                  If this argument is supplied
                     and is not nil, the tblnext entry counter
                     is adjusted so the following tblnext call
                     returns the entry after the one returned by this tblsearch call. Otherwise, tblsearch has no effect
                     on the order of entries retrieved by tblnext.
                  
                
             
         
         Return Values
         
         If tblsearch finds
            an entry for the given symbol name, it returns that entry in the
            format described for 
                     tblnext.
            If no entry is found, tblsearch returns nil.
