I don't know about Clark submitting a requirement in the 90's, but there is an existing SHARE requirement: SSLNGC03003 Compiler option to make BLOCK CONTAINS clause SMS sensitive
(Part of the Description) "The current default for when the BLOCK CONTAINS x RECORDS clause is omitted is for unblocked files. If this default is taken, the result is an unblocked file with very poor I/O performance. This may not be obvious since the JCL may be correctly coded, but any JCL BLKSIZE specification will be ignored without notification. Coding BLOCK CONTAINS 0 RECORDS is the preferred solution, since it allows DFSMS to pick blocking with the optimal BLKSIZE. This requirement requests a compiler option that would allow the default for when the "BLOCK CONTAINS" clause is omitted to be set to the same processing as the current handling of "BLOCK CONTAINS 0 RECORDS" instead of creating/reading unblocked files." * * * * * This was submitted in 2003 and in 2004, IBM responded with "ACCEPT". There is currently a "push" within the comp.lang.cobol group to get AS MANY AS POSSIBLE of existing Enterprise COBOL sites to submit a "Marketing REQUEST" that references this SHARE requirement and asking for implementation "sooner than later". I would suggest that ALL of those in IBM-MAIN who are interested in seeing this enhancement, should also contact their IBM marketing representative and have such a REQUEST submitted from your site. (And no, don't ask ME how to find an "IBM marketing representative") "Gilbert Saint-Flour" <usenet5...@yahoo.com> wrote in message news:<200905181748.44799.usenet5...@yahoo.com>... > On Friday 15 May 2009 04:47, Clark Morris wrote: > > > ....
