Additions

• INTO wa
  Assigns the read line to a work area wa.
• ASSIGNING <fs> [CASTING]

• REFERENCE INTO dref
  Assigns a reference to the read line of a reference variable dref.
• TRANSPORTING NO FIELDS
  Read line is not assigned.
• USING KEY key_name|(name)
  Declares statically or dynamically a (secondary) table key that determines the processing sequence.
• [FROM idx1] [TO idx2] [WHERE log_exp|(cond_syntax)]
  Limits the rows to be read by declaring of a lower and upper number idx1 and idx2 in the table index being used or by declaring a static condition log_exp or a dynamic condition in cond_syntax.
