WHY LRECL NEEDS TO BE 4 EXTRA THEN THE COBOL FILE LENGTH & WHAT IT CONTAIN IN THAT LENGTH?
Answer:
First thing is we can see this kind of differece only in VB
files not in fixed block files.
LRECL of VB file will contain the maximum record length of
a file + 4 bytes RDW(Record Descriptor Word) field which
gives the length of the record as the file contains
variable record lengths.
Example : if we have EMP-FILE VB file which contains 80
THRU 100 CHARECTERS
So the LRECL of this file is going to be 100+4 which is 104
bytes.
