- 11. Execution character set: • Certain ASCII character are unprintable which means they are not displayed on the screen or printer. • Those character performed other function aside from displaying text. Examples are backspacing moving to a newline or ringing a bell they are used in output statements. • Execution character set are always represented by a combination of backslash() followed by a character. • These characters combination are called as Escape sequence.
