an externally defined data structure is used to allow a pre-defined (normally field level definition) to be used to map the data in a data structure rather than defining it explicitly in the program
therefore if you want a data structure where the information is in the same format as one of your files then you could identify this to an rpg program using the following D spec
D DataStructure DS Likerec(Format)
this is for example particularly useful when describing key data structures, qualified data structure or input/output data structures for file handling
