This prints a specific system's extended description. This is called the "pink volcanoes string" in a comment in the original source, and the "goat soup" recipe by Ian Bell on his website (where he also refers to the species string as the "pink felines" string). For some special systems, when you are docked at them, the procedurally generated extended description is overridden and a text token from the RUTOK table is shown instead. If mission 1 is in progress, then a number of systems along the route of that mission's story will show custom mission-related directives in place of that system's normal "goat soup" phrase.

This routine works its way through the recursive text tokens that are stored in tokenised form in the table at QQ18, and when it finds token number A, it prints it. Tokens are null-terminated in memory and fill three pages, but there is no lookup table as that would consume too much memory, so the only way to find the correct token is to start at the beginning and look through the table byte by byte, counting tokens as we go until we are in the right place. This approach might not be terribly speed efficient, but it is certainly memory-efficient.

Print a character at the text cursor (XC, YC), do a beep, print a newline, or delete left (backspace). If the relevant font is already loaded into the pattern buffers, then this is used as the pattern for the character, otherwise the pattern for the character being printed is extracted from the fontImage table and into the pattern buffer. For fontStyle = 3, the pattern is always extracted from the fontImage table, as it has different colour text (colour 3) than the normal font. This is used when printing characters into 2x2 attribute blocks where printing the normal font would result in the wrong colour text being shown.
Arguments: A The character to be printed. Can be one of the following: * 7 (beep) * 10-13 (line feeds and carriage returns) * 32-95 (ASCII capital letters, numbers and punctuation) * 127 (delete the character to the left of the text cursor and move the cursor to the left) XC Contains the text column to print at (the x-coordinate) YC Contains the line number to print on (the y-coordinate) fontStyle Determines the font style: * 1 = normal font * 2 = highlight font * 3 = green text on a black background (colour 3 on background colour 0)
