Hi,

I am in a prodcution support team.
Many of our old cobol programs have been coded with

BLOCK CONTAINS 0 RECORDS.

and some program are coded with

BLOCK 0 RECORDS.

are they both equivalent?

Yes, and they both allow SDB, which is good....

Thanks for info.
but what is SDB?

Kaleel,

SDB stands for 'system-determined block '.

Hi as I already intoduced my, I am tuning our programs in my support work.
We have Easytrieve programs also in our scope.
Can any thing like BLOCK CONTAINS 0 RECORDS can be coded in them too. I am somewat new to Easytrieve.
I think I should have started this topic in that Easytrieve forum. But still since this requires both COBOL and Easytrieve information, I have put it here.
can any one suggest me something?

Just specify zero for the blocksize in the file statement....as in:
FILE SEQFILE FB(80 0)
