When i m writing variable length blocked sequential files, i m using the APPLY WRITE-ONLY clause for the file but it did not reduce much number of calls to Data Management Services and want to know about
mainframe testing software and about mainframe application modernization which are best colleges for them

Why did you choose to use this?

I would not expect much reduction in i/o . . .

Depending on the blksize, using a larger, more efficient blksize might decrease the number of calls, but you must make sure the blksize is efficient, not simply larger. . .
Have a good one

this link is for links to COBOL Tuning depending upon your IBM COBOL Release.

no need someone printing it for you,
read it yourself.
