Text Set Wildcards

Wildcards can also be applied to the text codes to control which codes are included. The colour text sets example that follows demonstrate the correct and incorrect use of wildcards.

In the case shown above, Agn will be allocated its own colour while all remaining codes beginning with Ag will be given the same colour. This is a good way of differentiating a single code from others that are similar.

In the second example above, wildcards are used incorrectly. Agn will be given the same colour as all of the other codes beginning with Ag.

This happens because the program processes the text set from top to bottom. Once it finds a match for a record, it will not look for another match. This should be remembered when using the Asc/Desc function.

Operations involving hatch sets are virtually identical to those with colour sets. For this reason a separate explanation is not given.
