DOS4GW &nbsp;is a 'dos extender'<br />
normaly Dos programs can only use 640 KB - space used for device drivers and resident programs RAM.<br />
most computers have more ram but dos can't access it.<br />
Dos extenders are switching the CPU into Protect mode and enables the posibility to use the complete ram.<br />
DOS4G stands for DOS 4 Gigabytes.<br />
and it is made and sold! by Rational as I know.<br />
when the Watcom company build their 32 bit C/C++ compiler they needed the posibility to switch to protect mode. They bought a version of DOS4G that has less &nbsp;features than the original but it can be distributed free. - W you can see stands for Watcom.<br />
For the most programs you must not explicit call DOS4GW most time it is enough to start the program that needs it but DOS4GW must be inside the search path or the current directory<br />
DOS4GW itself has no 'face' it is only used internaly by other programs.<br />

I downloaded DOS4GW to be able to play some nes games, but I don't know what to do with the file. &nbsp;When I type DOS4GW.EXE it says the syntax is wrong, that it is &quot;DOS4GW &lt;executable.xxx&gt;&quot;. &nbsp;So I typed that in and it says file not found. &nbsp;How do you load and/or execute this file?

C is a general-purpose, imperative computer programming language, supporting structured programming, lexical variable scope and recursion, while a static type system prevents many unintended operations. By design, C provides constructs that map efficiently to typical machine instructions, so it has found lasting use in applications that had formerly been coded in assembly language, including operating systems as well as various application software for computers ranging from supercomputers to embedded systems. It is distinct from C++ (which has its roots in C) and C#, and many later languages have borrowed directly or indirectly from C.
