Why is Cobol designed to READ FROM A FILE and WRITE TO A RECORD?

because multiple record definitions are allowed for an FD.
since they all start at the same address, there is no need to declare into which record to read a file.

but, since multiple records can be defined for a file, in order to have the proper length record written, we need to declare from which record a file is written.

There is something called as record id. A file can contain multiple records and while writing to an output file, this record id is taken into consideration. If not, records are overwritten.

Thanks Brenholtz,

I got many answers and urs makes lot of sense. I tried to search and none of the books or Online tutorials have this explaination. But I guess this is a good question.
Thanks Again

actually, the answer is: because that is the syntax.

I have never found the explanation I provided,
but it makes sense to me.

Another thought:
We read a file because we don't know before the read if there even is a record to be read.
