SpoolAid - Full-screen browser for spool file internals
SpoolAid is a tool which allows you to browse the internal structure of CP spool files. This tool is intended for use by application developers and system programmers who have a need to see the raw data in a CP spool file, normally obtainable by an application program via CP Diagnoses X'14, X'B8', and X'F8'. SpoolAid provides a full-screen, XEDIT-based display of the CP SFBLOK, SPLINK, and XAB control blocks. On a 370-based VM system (VM/SP, VM/HPO, or VM/ESA 370 feature), the SFBLOK and SPLINK represent data exactly as kept by CP. On an XA-based VM system (VM/XA, VM/ESA ESA feature, or z/VM), the SFBLOK and SPLINK represent data from the CP SPFBK and SPDBK control blocks as translated into VM/SP format by Diagnose X'14'.
SpoolAid can display any spool file which can be read via Diagnose X'14. You can have your choice of a formatted display (which is the default) or an unformatted display of the spool data. A formatted display is tailored to the type of spool area being viewed -- for example, an SFBLOK display will show the name and value of each SFBLOK field; a SPLINK display will show the name of each CCW encountered; an XAB display will show the name of each Output Processing Text Unit found (if the XAB was created by RSCS or PSF or an equivalent program). An unformatted display shows a hexadecimal and EBCDIC "dump style" view of the selected spool area.
SpoolAid should run on any version of z/VM. It should also run on any release of older VM versions, such as VM/SP, VM/HPO, VM/XA, and VM/ESA (both 370 and ESA features). In the 20 years since its initial release, SpoolAid has run on VM versions back to VM/SP Release 4. The current version of SpoolAid is developed and tested on z/VM Version 5 Release 2.0. The author does not have access to back-level VM systems for testing.
SpoolAid requires no installation other than placing the files in the package on an accessed mini-disk or SFS directory. If you desire to perform some tailoring of the display, you may copy the file SPOOLAID SAMPROF to SPOOLAID PROFILE and change it as necessary, guided by the comments in the file. Note that if you wish to use the default settings, you do not need the SPOOLAID PROFILE file.
SpoolAid can be invoked from the CMS command line or from within RDRLIST via the SA command. In order to get started, type
HELP SPOOLAIDfor a menu of help on various topics about the SpoolAid tool. Type
HELP SA or SA ?to go directly to help for the SA command. Detailed help for the SFBLOK, SPLINK, and XAB displays is available from the "HELP SPOOLAID" menu or via PF1 from within the SpoolAid displays for those control blocks.
SpoolAid is available as SPOOLAID PACKAGE internally within IBM on VMTOOLS and externally via the download package area on the z/VM pages on the web at http://www.vm.ibm.com/download. Version 2.59 of SpoolAid is also shipped with RSCS Version 3 Release 2 as a service aid.
