TCC top-level constant
Tabulation Centred On Character.
Representation: CSI n1;n2 \x20 \x63
No parameter default value for n1 Parameter default value: n2 = 32
TCC causes a character tabulation stop calling for alignment of a target graphic character 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, and the target character about which centring is to be performed is specified by n2. TCC causes the replacement of any tabulation stop previously set at that character position, but does not affect other tabulation stops.
The positioning of a text string aligned with a tabulation stop set by TCC will be determined by the first occurrence in the string of the target graphic character; that character will be centred upon the tabulation stop. If the target character does not occur within the string, then the trailing edge of the first character of the string will be positioned at the tabulation stop.
The value of n2 indicates the code table position (binary value) of the target character in the currently invoked code. The permissible range of values is 32 to 127.
Implementation
const String TCC = ' c';
