Alan - COBOL permits the same name to be used in multiple places and they
can even have different definitions. You just have to qualify the name
when you use it. i.e. AccountNo of MyRecord.

Hi Thomas
I came from coding in COBOL, where more than one field with the same

name was a compile error

You are correct
ANY field with the same name - a stand-alone filed - a field in another

file, when a file is read - the data in those fields are all populated if
they are the same name and size

I have grown into a love hate relationship with this
MOST of the time - it can kill you
However - there ARE some times it can be great

Subject: [EXTERNAL] Question on file reading

In RPGIV - maybe this is true in free format - if a Data Structure is

defined with the exact names and sizes of the fields in a file when the
file is read is the data structure automatically loaded?

Personally I have never seen this before.
