Instructions that enable or disable certain characteristics of the Braille code, or perform actions if the condition is TRUE, always start with the letter X (capital X). For these instructions to be executed correctly, the command interpreter must arrive at them and not be interrupted beforehand (short circuit). If you use these instructions, it is useful to enclose the others within a "(...)" block. Below is a list of all available instructions.
- X1, X2, X3, X4, X5 - Write n characters
This flag allows you to ascribe "n" code braille cells in front position to some prefixes (number and upper case). For example, if you use the text string "biblos", you transcribe in Braille as "36 36 36 12", and as a condition you use "X3", in normal situations the transcription will be "36 36 36 12"; if the word "Biblos" has a capitalized initial the transcription will be "36 36 36 46 12". Without condition "X3" the transcription would be "46 36 36 36 12".
- Xc - Excludes signholders
This flag inhibits the presence of a case prefix.
- Xn - Exclude number marker
This flag inhibits the presence of the number prefix.
- Xm - Merge Numbers
This flag allows you to have a numerical continuation when the numbers are interrupted by a symbol, to prevent the mark from being placed on the numbers following the symbol. For example, the Xm flag is used in the "/" symbol. The transcription of the numbers '1/2' will be '3456 1 34 12'. Without the Xm condition the number 2 would also have the number prefix.
- Xb - Interrupt code
During document preparation, if the Braille code where this flag is used falls at the end of the line, the line will be broken near the code. Otherwise, the preparation attempts to hyphenation the words or identify a useful space.
- Xd - Duplication code
During document preparation, if the Braille code where this flag is used falls at the end of the line, the code will also appear on the new line, then it will be duplicated.
- Xu - Joining flags
This is a complementary flag to the Iu instruction (Unifiable Index with Flag). The Iu instruction is useful for eliminating the space or spaces between words. For more information read the relevant help.
