Version analysis of RUGAL

This code appears in the following versions (click to see it in the source code):

Code variations between these versions are shown below.

Name: RUGAL Type: Variable Category: Text Summary: The criteria for systems with extended decription overrides Deep dive: Extended system descriptions Extended text tokens
This table contains the criteria for printing an extended decription override for a system. The galaxy number is in bits 0-6, while bit 7 determines whether to show this token during mission 1 only (bit 7 is clear, i.e. a value of &0x in the table below), or all of the time (bit 7 is set, i.e. a value of &8x in the table below). In other words, Teorge, Arredi, Anreer and Lave have extended decription overrides descriptions that are always shown, while the rest only appear when mission 1 is in progress. The three variables work as follows: * The RUPLA table contains the system numbers * The RUGAL table contains the galaxy numbers and mission criteria * The RUTOK table contains the extended token to display instead of the normal extended description if the criteria in RUPLA and RUGAL are met See the PDESC routine for details of how extended system descriptions work.

Code variation 1 of 1Related to an advanced feature

The source disc release of the 6502SP version overrides the extended system description for Lave, and the Executive version overrides both Lave and Riedquat. The Master version also has an override for Lave, but this time it's only for Lave in galaxy 16 (i.e. the 17th galaxy).

This variation is blank in the Disc (docked) version.
