Open M for DOS and Windows (DTM) Version 6.4
Summary of Features
More General Naming and Subscripting Conventions
You Get More Flexibility in Handling Subdirectories and Namespaces
Open
M (DTM) now accepts subdirectories with a "." in their names and permits
namespaces to have a "-" or "%" in their names.
Null Subscripts Are Now Supported
If you enable null
subscripts, %dsverify now accepts null subscripts without reporting them
as an error.
Improved SPX Networking
Exponential SPX Network Numbers Are Now Supported
Some types
of addresses containing ``E'' now work, with the ``E'' interpreted as
indicating exponential.
SAP Locating Has Been Improved
SAP for a single server is now
correctly located even when there are multiple servers.
Client Disconnects after "No Send Buffers" Have Been Eliminated
SPX receive and send buffers can be increased. When not specified,
default settings are used. You can eliminate occurrences of the error
``No send buffers available'' by using the recommended settings.
LAT Buffer Overruns Have Been Eliminated
Open M (DTM) now
checks for and prevents LAT buffer overruns.
Key Handling Has Been Improved
You get better cursor and
arrow key handling on terminal-based form drivers.
Control Characters Have Been Made Loadable
You can now
load global save files that contain embedded control characters and you
can recover control characters (including the new-line character) that
have been saved as part of a global node's value.
Utility to Restore Journal from Open M (DTM) 4.8 into 6.4
InterSystems now provides a utility that enables you to restore a
journal you created in Open M (DTM) 4.8 into Open M (DTM) 6.4. Moving
directly to the newest release is almost effortless.
Utilities Have Been Improved
$ZH
The %ZH utility is now accurate to within 0.1 second per
day.
%dstest
InterSystems has improved the %dstest utility in the
following two ways:
- The utility no longer fails with a "Divide by zero" error when
run against an empty dataset.
- The utility now gives meaningful results when run in the opposite
direction.
%mhaltsys
%mhaltsys will not error out if a job disappears.
You get a more secure and stable system.
%netlog
You can now use %netlog to purge the network log file.
You get more memory control.
%ixedit
%ixedit no longer leaves working variables around. You
get even more memory control.
%g and %glist
The %g and %glist utilities now support up to 25
subscripts, a substantial increase over previous DTM releases. An error
message is printed if a global has more.
Inconsistencies Have Been Eliminated
Case-handling
inconsistencies in the MUMPS.DEV file have been eliminated.
Clusterport Support
You can now use Clusterports under
Windows 95 with Open M for DOS and Windows (DTM).
Login and Startup Obstacles Have Been Removed
You Get Better Error Reporting for EMM Startup Errors
If your
system has no EMM, that fact will be properly reported.
ZUSE No Longer Inhibits Logins
ZUSE no longer interferes with
logins on devices in the 100-131 range. It continues to work correctly
on devices in the 200 series, i.e., smartport devices.
Display Capabilities Have Been Improved
Error Trap Now Saves Code
The error trap now saves the line of
code in which the error occurred, so you can display it.
Device Parameters Can Be Edited
InterSystems now provides a new
routine that enables you to modify device parameters before displaying
the current settings.
Lock Examine Has Been Made More Natural
The utility system
managers use to find locked nodes now defaults to decimal, rather than
hex.
Machine Configuration Information More Readily Obtainable
For previous releases, when you contacted the InterSystems Worldwide
Support Center, you were asked to provide extensive information about
your machine configuration. InterSystems now provides a new utility that
will generate a text file containing most of this information.
