program t79_strfield;

{ t79 -- a STRING field written through a DI-addressed record element.

  CALC.INC:162, immediately after the set:

      Contents := '';

  Contents is String[70].  Within `with Sheet[I,J] do' the record's address
  is in DI, so the counted-string copy has to store <len><chars> through it,
  truncated to the field's capacity.  Also covers a string VARIABLE source
  (strstore with DI as the destination), a plain record field (symbol+off),
  and the neighbour N to prove the copy stops at the field.

  A short literal must set the length to the SOURCE length, not the capacity:
  storing the capacity would print the bytes that happen to follow the
  literal. }
