Open M [ISM] for OpenVMS Alpha
Version 6.2 Summary of Features

Starting Open M

• To better identify Open M and the environment in which it is running, Open M now writes a record to the mconsole.log file each time an MSTART is performed. The record specifies the Open M version number, the operating system name and version, and the node name.

I/O

• Open M [ISM] for OpenVMS Alpha now supports magnetic tape block sizes of up to 32768 bytes.
• Open M [ISM] for OpenVMS Alpha now supports a total of 92 pairs of interjob communications devices that can be accessed via the OPEN, USE, and CLOSE commands.

Networking

• InterSystems has enhanced the Open M caching structure, leading to significantly improved performance when there is a large number of network users.
• InterSystems has added a debugging feature to Open M networking to help the system recover from sequence desynchronization problems between the client and server of an ISNET connection (a condition where the server expects a different sequence number than the client is sending).

Journalling

• The GETREC entry point of the JRNUTIL utility now returns the timestamp associated with each record in JRNODE(1,1,3).

Utilities

• More consistency has been provided in exiting some utilities, specifically those that prompt for a directory name. All of the following will allow you to exit from these utilities: quit, exit, stop and "^".

M Language Extensions

• InterSystems now supports $ZU(106), a function that allows you to store temporary information in a memory buffer instead of in globals.
• To accommodate long tag and routine names, the $ZE special variable now returns up to 96 characters.
