>From "DFSMS Macro Instructions for Data Sets" 2.3.9 CLOSE--Disconnect Program and Data (BDAM, BISAM, BPAM, BSAM, QISAM, and QSAM)
The CLOSE macro creates output data set labels and allows you to position volumes. The fields of the data control block (DCB) and DCBE are restored to the condition that existed before the OPEN macro was issued, and the data set is disconnected from the processing program.

I may have the order differntly, but the system does not remember pre-open DCB state and does not return it to that state at close time. At least I don't remember it ever working that way. ---------------------------------------------------------------------- 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
