MicroVMS Release Notes Version 4.1

This document, the "MicroVMS Release Notes Version 4.1," published in January 1985, provides essential information for users updating their MicroVMS system from Version 4.0 to 4.1.

Key areas covered include:

1. Installation Instructions: Detailed steps for installing the Version 4.1 update kit, which is distributed on three RX50 floppy diskettes. It emphasizes critical prerequisites like backing up the system disk, ensuring sufficient free disk space (minimum 7400 blocks), logging in as SYSTEM, and verifying system account authorization limits and global section/page availability. Post-installation tasks involve purging old system files to reclaim space and regenerating the Stand-Alone Backup kit.
2. Problems Resolved by Version 4.1: A list of bugs and issues fixed in this version, including:
   • Corrections to the Mount Verification canceling routine that caused console hangs.
   • Improved protection for storage bit maps and master file directories (MFD) on Structure Level 1 Disks.
   • Multiple fixes for the System Dump Analyzer (SDA), addressing error message display and abnormal exits.
   • Proper functionality of the /ACCOUNTING qualifier during image installation.
   • Resolved issues in Record Management Services (RMS) related to remote command files, SET VERIFY command, and image input verification.
   • Correction to $CHANGE_ACL and $MGBLSC system services to properly respect the BYPASS privilege.
   • The RMS$RENAME service now correctly returns a "File Not Found" status for nonexistent files.
   • A new mandatory order for File Definition Language (FDL) primaries (e.g., TITLE, IDENT, SYSTEM) to resolve syntax ambiguities.
3. Current Problems and Restrictions: Known issues that remain in Version 4.1:
   • A "BAD_LRL" error may occur with SORT for certain sequential stream files where record control characters span disk blocks (can often be ignored or worked around).
   • The auto-login facility does not work on disconnectible terminals.
4. Notes to Published Documentation: Provides corrections and supplemental information to existing MicroVMS manuals, including:
   • Detailed guidance on how group logical names are created at system startup in MicroVMS Version 4.0, requiring modifications to SYSTARTUP.COM procedures.
   • A correction to the syntax description of the ALLOCATE/GENERIC qualifier.
   • Clarification that MicroVMS Mail allows sending to multiple distribution lists, not just one.
5. Appendices:
   • Appendix A: Lists the detailed descriptions of mandatory updates and patches included in Version 4.1.
   • Appendix B: Describes two VAX/VMS Run-Time Library routines, OTS$MOVE3 and OTS$MOVE5, which were inadvertently omitted from other documentation.
   • Appendix C: Provides additional MicroVAX I Bootstrap support, explaining how to create a special console floppy diskette to boot from secondary Mass Storage Control Protocol (MSCP) controllers and place MicroVMS on a new system disk.
