There are people in every area who know less than they should. When I see people criticizing any group with such a broad statement, I wonder where the problem really lies. >I knew one who had just copied the same FD's for many years, just >changing the LRECL, as needed, and leaving BLOCK CONTAINS 1 in. He wouldn't have survived where I worked as an applications programmer starting in 1970. At that time, *all* of the programmers knew that they had to specify block contains 0 in the FD. The problem with specifying a blocksize in the DCB predates SDB by many years. When the program specifies a blocksize in the DCB, it cannot use the blocksize of the input data set. -- Tom Marchant ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to [email protected] with the message: GET IBM-MAIN INFO Search the archives at http://bama.ua.edu/archives/ibm-main.html
