Pattern Matching
Appendix A 297
Patterns without expression anchoring can match any substring within
the input line. Therefore, patterns such as:
this is number<#.num>
are treated in the same way as:
<*>this is number<#.num><*>
Separator Characters
The separator characters used in <_> and <@> can be specified for each
pattern. The user enters the separators in the pattern definition mask;
default characters are the blank and tab characters.
Case Insensitive Mode
VPO allows to specify case sensitive or insensitive mode for each pattern.
The user sets the mode in the pattern definition mask.
