What is the benefit of using Externally Described files
over Internally
Described?

Answer Posted / remya

Internally described file-A flat file is called internally
or program described file.this flat file can be used in any
program but the fields or structure can be described only
within that particular pgm.

externally described file-Any file that has dds entries or
specified structure is called externally described file.

benefit of externally described file is that we can directly
read, write, update, delete the records of file in the
pgm.but in the case of program described files we can do the
above specified file operation only with the help of a data
structure(except read).
