I have a variable length file in which four different type of records can come each type has different rec length.

Each of the four records maps to specific copy book and we have a filler in each of the copy book.

Now if i print the length of each record then length should be actual length of pariticar record without filler or A particular record type length will alway be fixed.

say record type1 has :225 charters leaving filler
will it be always 325(225+filler 100) for record type1 or it may be varying

jajularamesh,

Why do the copybooks defining the 4 types of records have FILLER's?

If you define a record structure (area) and put a filler on the end, the length of the record structure (area) will include the filler.

In the FD Section, all records defined for a file ORIGIN at (REDEFINES the) first record definition.

Thanks Dick Brenholtz

Actually my reguirement is to generate millions of records by taking a set of 10 records.

As i am modifying the input file actual filler length is getting discarded and i am getting records with atleast a difference of 100 bytes (which is filler length) so i got the doubt whether we will be getting fixed lenth or not.

Actually Preserve on should be used before modifying a file.otherwise i am getting difference in lengths

See layout of each record type is different.

but for each record type filler is also present which of 100 bytes length.

when i edited the input data set then the actual length of the record types getting chaged.

Recordtype1:say 500 bytes
Recordtype1:say 600 bytes
Recordtype1:say 700 bytes
Recordtype1:say 800 bytes

So always for record type1 i should get as 500 bytes but i am not getting 500 bytes as i edited the dataset(i,e i deleted some of the from the input file)

when i used this file i am getting the mismatch in the length of the records.

But i could not understand the reson for getting different length for the same recordtype

Now i just copied some of the required records to another dataset using sort and when i ran the same program

Now i am getting the correct record length for a specfic recod type.
Recordtype1:say 500 bytes
Recordtype1:say 600 bytes
Recordtype1:say 700 bytes
Recordtype1:say 800 bytes

hope from this you can understand what the exact problem was

jajularamesh,

What are you trying to do and how?

This is application programming forum.

Your first posts talks of copybooks with fillers.

Now you are talking about EDITing the file and having problems. With ISPEdit, Fileedit?

Please, determine what you have to do and how you want to do it.
Then post it in the proper forum. If you don't know or can't determine the problem, post it in PROBLEM DETERMINATION forum.
thx,

Jajularamesh,

Please be clear in what you are asking...If you are unable to explain your requirement, atleast tell us what you were trying to do and what happened ?

record length of any record (be it a copybook or a WS- group) depends on how it is defined. The layout could have "OCCURS DEPENDING ON <argument>" clause which may vary the length of the record at run time - depending on the count mentioned in the <argument>.

Does this answer your question ? If not, explain us clearly.

Thanks,
Phantom
