Sneak preview of UNICOS 10
New, improved, with bleach . . .
by Tom Parker
SCD plans to install a new version of UNICOS, version 10.0, on NCAR Cray computers by mid February '98. Most of the changes are "under the hood,"
but there are a few items (mostly good) that users might be interested in.
New features and options
Fortran rules for make and nmake changed:
The Fortran rules for make and nmake have been changed to use F90 as the default.
sinclude added to make(1) command:
The make(1) command includes the IRIX sinclude functionality in UNICOS 10.0.
If the string sinclude appears at the beginning of a line in a makefile,
followed by a blank space or a tab, then the rest of the line is assumed to
be a filename and will be read by the current invocation after substituting
for any macros.
Ability to disable core files:
The limit command has been changed to allow you to disable the creation of
core files. For example:
/usr/bin/limit -d nocore -p 0 -v
New vi tagstack feature:
A new tagstack feature has been added for vi that allows you to track backward
through up to 20 tag jumps. This is useful when examining unfamiliar
New option for target:
A new -s option has been added to the target. This option prints only
the machine subtype field. If you do not specify the -s option, target prints the subtype field with the CRAY prefix.
Error message for rm -f option:
The -f argument to the rm command now displays an error message if a file
or directory cannot be removed. This change complies to POSIX
ls command indicates multilevel symbolic links with -le options:
With the -le options, the ls command now indicates a multilevel symbolic
link by using *> instead of -> to display the link's contents. For example,
the result of
ls -le /usr/mail would be:
lrwxrwxrwx 0 1 root bin 13 Dec 22 1997 \
/usr/mail *> /usr/mail.mld
- Support for CF77 Programming Environment ending:
The CF77 Programming Environment (PE) is no longer available with UNICOS
operating system releases. Support for the CF77 PE ended on 30 September 1996.
- File manager, xfm not supported:
The xfm(1) utility is a prototype that provides a visual tool, based on the
X Window System, to perform file management for the UNICOS system.
- Support removed for libwatch.a library:
The libwatch.a library and the watchword(7) man page are no longer
supported. They have been removed with the CDBX debugger and CF77 compiler.
