Why complicate your logon PROC? I prefer just the ISPCTLx. And, just allocate and de-allocate as your file tailoring requires. But, teto. - Ted MacNEIL eamacn...@yahoo.ca Twitter: @TedMacNEIL

To preallocate these data sets to VIO, include the DD statements in _Figure 48_ (http://publibz.boulder.ibm.com/cgi-bin/bookmgr_OS390/BOOKS/ispzpc80/1.4.9?SHELF=EZ2MZ921&DT=20090610205143#FIGTDS) in the TSO LOGON procedure. Preallocation of these data sets to VIO is not mandatory; ISPF automatically allocates them to real data sets if required. However, preallocation is recommended, because it reduces overhead and eliminates potential problems from insufficient space. //ISPCTL0 DD DISP=NEW,UNIT=VIO,SPACE=(CYL,(1,1)), // DCB=(LRECL=80,BLKSIZE=800,RECFM=FB) //ISPCTL1 DD DISP=NEW,UNIT=VIO,SPACE=(CYL,(1,1)), // DCB=(LRECL=80,BLKSIZE=800,RECFM=FB) . . . //ISPCTLW DD DISP=NEW,UNIT=VIO,SPACE=(CYL,(1,1)), // DCB=(LRECL=80,BLKSIZE=800,RECFM=FB) //* In this section of JCL, there is one DD for each screen //* defined, based on the value of keyword MAXIMUM_NUMBER_OF_ //* SPLIT_SCREENS in the configuration table. //* The DD name is in the form ISPCTLx, where x can be //* 1-9, A-W.

When allocating to VIO, make sure that enough auxiliary storage is dedicated to VIO so that system availability is not affected. 2. Use of the BUFNO parameter on allocation of ISPF libraries is not supported. 3. The ISPF temporary data set default names associated with the ISPCTLx are SPFTEMPx .CNTL, respectively, where x= value 0-9, A-W. 4. The ISPF temporary data set default names associated with the ISPWRKx are SPFTEMPx.WORK, respectively, where x= value 1-9, A-W. 5. The ISPF temporary data set default names associated with the ISPLSTx are SPFTEMPx.LIST, respectively, where x= value 1-9, A-W. 6. The ddnames ISPWRKx are used by ISPF for file tailoring services with ISPFILE allocated to a PDS. The ddnames ISPLSTx are used for generated listings. 7. The ddname ISPCTL0 is used with the edit SUBMIT command. The ddnames ISPCTLx are used with ISPF compress (both interactive and the LMCOMP service) and ISPF background (option 5), and for processing the file tailoring service FTOPEN TEMP. 8. ISPCTL1 is a required ddname when using SCLM. The data set should be allocated as an ISPF temporary data set for SCLM foreground processing and should be added to the FLMLIBS skeleton for batch processing.
