When you choose a rule, an associated screen is displayed in which you can define the rule.
5.10.3.1 Case Rules
The case rules are defined as follows:
• No rule—ignored.
• Search and replace—replaces all instances of the match string. (Note that this rule
cannot fail.)
• Match at index—matches the match string at a specified index.
• Match and replace at index—matches the match string at a specified index and
replaces/changes it.
• Replace at index—replaces/changes unspecified data in a given range.
• Add barcode prefix/suffix—adds a global prefix or suffix.
• Verify barcode size—verifies the bar code size. This rule should generally be assigned
first, before creating subsequent rules.
Translation information about the status of each case/rule is displayed in the scan log file
(see “Scan Log File” on page 140) when enabled. This is useful if a case fails, and you are
trying to determine why a rule is failing.
Note: Keep in mind that the effects of previously applied rules must be taken into account
when creating subsequent rules. For example, if the bar code size is important, it
should be checked before any rules that might change the size are applied.
