What is the benefit of using Externally Described files
over Internally
Described?
Answer Posted / narender
Well when you create any data base file( eg PF) using the
STRSEU and save and compile the file you will get the DDS
called Data Description Specification of that file. The
file which have the DDS is called Externally Described file
and it must exists before you use it in any program. The
file for which no DDS exist are called Internally or
Programed described files. These files are defined in the
program itself along with the data fields so it needs some
effort in coding also.
