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.

Please do let me know in case of any comments/queries.

Answer / narinder

In JCL, LRECL NEEDS TO BE 4 EXTRA THAN THE COBOL FILE LENGTH in case of Variable Block File. Since length of each record varies in the file, the first 4 bytes contains the length of the corresponding record.

Please correct me if I am wrong.
