EMIT

( x -- )

If x is a graphic character in the implementation-defined character set, display x. The effect of EMIT for all other values of x is implementation-defined.

When passed a character whose character-defining bits have a value between hex 20 and 7E inclusive, the corresponding standard character, specified by 3.1.2.1 Graphic characters, is displayed. Because different output devices can respond differently to control characters, programs that use control characters to perform specific functions have an environmental dependency. Each EMIT deals with only one character.
