If you use a data pattern character that is not defined as a pattern character,
the Don't Care attribute is always selected. Use the Flush attribute to flush the
found data from the host data. Use the Include attribute include the found data
in Store operations. The Include attribute is selected by default.
If you use a data pattern character that is defined as a pattern character, the
Pattern Character attribute will be selected by default, and the background of
the inc mnemonic will be light green. To change it to a wild card character,
right-click the character. The attribute pop-up menu appears. See Figure 142.
Figure 142. Pattern Character Pop-up
The Pattern Character attribute is selected by default. To use the data pattern
character as a wildcard, select the Don't Care attribute.
Minimum Length: Defines the minimum length the pattern must have. If the
data pattern is set to scan for numerals using a pattern character, it must find
at least n numerals (the value set by this property) before a match is
considered.
Maximum Length: Defines the maximum length the pattern may have. If the
data pattern is set to scan for numerals using a pattern character, it only
scans for a maximum of n numerals (the value set by this property) before a
match is made.
Delimiter
Use delimiters to find data easier. You can look only for a start delimiter, end
delimiter, start and end delimiters, or auto delimiter.
Start: When you enable Start, a pattern match occurs only when the Start
character is found. The Start character may be a single character or a pattern
character, and it has the Flush and Include attributes.
End: When you enable End, a pattern match occurs only if the End character
is found at the end of the data pattern and the maximum length is not
exceeded. The End character may either be a single character or a pattern
character, and it has the Flush and Include attributes.
Auto: When you check the Auto check box, the pattern considers the first
character found to be the start and end delimiter. See the following example.
NOTE: In the following example, items enclosed in <> indicate datastream
adapter objects like Pattern, Pattern Character, etc. Random host
data is indicated by "...." preceding and/or following the sample data.
