Many of the text elements are found in the 1988 ISO technical report TR 9537 Techniques for using SGML, which in turn covers the features of early text formatting languages such as that used by the RUNOFF command developed in the early 1960s for the CTSS ( Compatible Time-Sharing System ) operating system: these formatting commands were derived from the commands used by typesetters to manually format documents.

Many customers kept using their old software and one of the features of the later System / 370 was the ability to switch to emulation mode and back under operating system control.

Many wheeled IFVs can extract themselves from a battlefield with specialised run-flat tires when not operating in difficult terrain, while an IFV with damaged tracks would require its tracks repaired in the field or an armoured recovery vehicle to tow it out.

Many operating system environments allow dynamic linking, that is the postponing of the resolving of some undefined symbols until a program is run.

Many of Lisa's operating system advances would not appear in the Macintosh operating system until System 7 or later.

Many embedded systems and RTOSs, however, allow the application itself to run in kernel mode for greater system call efficiency and also to permit the application to have greater control of the operating environment without requiring OS intervention.

Many disk operating systems maintain a count of the number of references to any particular block or file.

Many relays use an electromagnet to operate a switching mechanism mechanically, but other operating principles are also used.

Many space observatories have already completed their missions, while others continue operating, and still others are planned for the future.

Many software crackers have later grown into extremely capable software reverse engineers ; the deep knowledge of assembly required in order to crack protections enables them to reverse engineer drivers in order to port them from binary-only drivers for Windows to drivers with source code for Linux and other free operating systems.

Many US states also have requirements for vehicles operating on public highways.

Many other word processing applications exist, including WordPerfect ( which dominated the market from the mid-1980s to early-1990s on computers running Microsoft's MS-DOS operating system ) and open source applications OpenOffice. org Writer, LibreOffice Writer, AbiWord, KWord, and LyX.

Many lasers emit beams that approximate a Gaussian profile, in which case the laser is said to be operating on the fundamental transverse mode, or " TEM < sub > 00 </ sub > mode " of the laser's optical resonator.

Many servers take a long time for the hardware to start up and load the operating system.

Many computer operating systems have included speech synthesizers since the early 1990s.

Many modern operating systems directly support both time-sliced and multiprocessor threading with a process scheduler.

Many implementations of C and C ++ provide support for threading on their own, but also provide access to the native threading APIs provided by the operating system.

Many North American transportation planners reserve streetcar for traditional vehicles that operate exclusively in mixed traffic on city streets, while they use light rail to refer to more modern vehicles operating mostly in exclusive rights of way, since they may operate both side-by-side targeted at different passenger groups ..

Many believed privately owned power companies were charging too much for power, did not employ fair operating practices and were subject to abuse by their owners ( utility holding companies ), at the expense of consumers.

Many parts of the operating systems remained written in ZetaLisp and Flavors ( or New Flavors ).

* Many consumer-end laptop computers are made to support only one version of Microsoft Windows by limiting production of device drivers for that model for only the particular operating system.

Many of today's operating systems have hundreds of system calls.

Many companies have systems, particularly in R & D, which work more or less well, depending upon size and actual belief in the policy on the part of administration, as will be abundantly apparent in subsequent quotations.

Many of the suggested systems seem to have only the most tenuous relationship to the language structures that they purport to represent.

Many school systems now employ school psychologists and child guidance specialists.

Many religions, whether they believe in the soul's existence in another world like Christianity, Islam and many pagan belief systems, or in reincarnation like many forms of Hinduism and Buddhism, believe that one's status in the afterlife is a reward or punishment for their conduct during life.

Many cultures have attached importance to astronomical events, and the Indians, Chinese, and Mayans developed elaborate systems for predicting terrestrial events from celestial observations.

Many stories have developed since the founding long ago to become a part of America's folklore and cultural awareness, and non-native American folklore especially includes any narrative which has contributed to the shaping of American values and belief systems.

Many diseases are transmitted by poorly functioning sewage systems.

Many systems became quite sophisticated in graphic presentation, especially considering that the system was confined to ASCII codes.

Many civilizations and societies have devised a calendar, usually derived from other calendars on which they model their systems, suited to their particular needs.

Many ciphers are based on publicly known algorithms or are open source, and so it is only the difficulty of obtaining the key that determines security of the system, provided that there is no analytic attack ( i. e., a ' structural weakness ' in the algorithms or protocols used ), and assuming that the key is not otherwise available ( such as via theft, extortion, or compromise of computer systems ).

Many worms that have been created are designed only to spread, and don't attempt to change the systems they pass through.

Many systems for generating musical scores actually existed well before the time of computers.

Many ( but not all ) computer systems use extensions in file names to help identify what they contain, also known as the file type.

Many modern computer systems provide methods for protecting files against accidental and deliberate damage.

Many systems have unintentionally resulted in the first possibility.

Many religious and mythological systems contain myths about a paradise.

Many systems of collation are based on numerical order or alphabetical order, or extensions and combinations thereof.

Many large cable systems have upgraded or are upgrading their equipment to allow for bi-directional signals, thus allowing for greater upload speed and always-on convenience, though these upgrades are expensive.

Many other coordinate systems have been developed since Descartes, such as the polar coordinates for the plane, and the spherical and cylindrical coordinates for three-dimensional space.

Many small-format digital SLR camera systems allow using many of the same lenses on both full-frame and “ cropped format ” cameras.

Many of the people involved with INGRES became convinced of the future commercial success of such systems, and formed their own companies to commercialize the work but with an SQL interface.

Many results in classical thermodynamics are not easily applied to non-equilibrium systems.

Many patented their systems such as Dee Dee Chandler of New Orleans 1904-05.

Many of the concepts in dynamical systems can be extended to infinite-dimensional manifolds — those that are locally Banach spaces — in which case the differential equations are partial differential equations.
