Hi,

Can you tell me the concept of variable blocked dataset. In Cobol program File Description,
I had given like this

Record is varying from 80 to 1200 characters Depending on wk-length

After declaring like this what is the record length I have to declare below in using PIC clause

I dont know what this wk-length does

My requirement is I have to use an input file with variable record length

that is for the first run i may use a file with record length 80 (VB)
then for the second run I may use a file with record length 400(VB)

Thanks in Advance
Regards,

Senthil,

Have you mentioned "Record is varying from 80 to 1200 characters Depending on wk-length " for a file definition or is it defiened for a variable table entry ??? Question

Senthil,

For variable blocked files, you need to define it as follows. Note that it starts from 1 instead of 80 as shown in your example.

Hi E,

I noticed that the text of your post stated something different than its title implied. Also in the text of the post you mention that the records vary from 80 to 1200, then you follow that by saying that the 1st run will have a file with 80 byte records, and the 2nd run will have a a file with 400 byte records.

This seems to imply that the records in these 2 files will all be 80 and 400 bytes respectively, in spite of the fact that you say they are "VB". Am I right?

I also note that you don't mention Record or Block Descriptor Words (RDW/BDWs) that identify a record a V or VB. Are you dealing with true IBM variable length records or are they merely in files that contain records of differing lengths? Perhaps you can send along a few records to illustrate.

Regards, Jack.
