lookup.ssi
The lookup.ssi file provides a link between codes found in a string file description field and a pattern defined in the patterns file. It also contains a default pen number for plotting the fill pattern. Note that this pen number will only be used if the pen number defined for the fill attributes of the entity is defined as 0 (zero).
Each line in the file may have at least 2 but possibly 3 fields delimited by commas. The first field is the code from the string file description field for which a pattern is to be found. The second field is the actual name of the pattern. A pattern of this name must be defined in the pattern file in use, usually SSI_ETC:patterns.ssi. The third field, if it is present may contain a specifier of the form pen=nn to define the pen number which is to be used when this pattern is drawn. Lines which begin with # character are ignored and are treated as characters.
