Terminal control/Coloured text: Difference between revisions

=={{header|Forth}}==

ANS/ISO Forth does not specify how screen color is handled. This demonstration creates a set of commands for an ANSI terminal that give the programmer control of text color.

DECIMAL

( support routines)

: TEXT ( color ) 30 + ATTR ; ( use: YELLOW TEXT )

: BACKGROUND ( color ) 40 + ATTR ; ( use: BLUE BACKGROUND )

With the code loaded into Forth, color control is a part of the language

<lang forth>WHITE TEXT BLUE BACKGROUND ok

BLUE TEXT BOLD ATTR ok
