What Forth?

FORTH, a computer language, has been described as many things. For example, L. Brodie, in his book, Starting FORTH, says “Forth is many things: a high level language, an assembly language, an operating system, a set of development tools, and a software design philosophy.” This might be true (I didn’t understand of word of it the first time that I read it!), but what does this mean to us in CATS? First of all, Forth is available for almost nothing for all of the Sinclair machines (TS-1000, 2068, and QL) at very low prices (a public domain version is also available for MS-DOS machines). Second, the system occupies a relatively few bytes. Third, it is a challenge to learn to use, and will force you to better understand how computers make any kind of program work.
