TAC top-level constant

String const TAC

Tabulation Aligned Centred.

Representation: CSI n \x20 \x62

No parameter default value.

TAC causes a character tabulation stop calling for centring to be set at character position n in the active line (the line that contains the active presentation position) and lines of subsequent text in the presentation component. TAC causes the replacement of any tabulation stop previously set at that character position, but does not affect other tabulation stops.

A text string centred upon a tabulation stop set by TAC will be positioned so that the (trailing edge of the) first graphic character and the (leading edge of the) last graphic character are at approximately equal distances from the tabulation stop.

Implementation

const String TAC = ' b';
