Syntax for Message Pattern Matching
Appendix A292
Variables The matched string can be assigned to a variable that you can use to
recompose messages or as a parameter for action calls. To define a
parameter, add the string: .parametername before the closing bracket.
For example, the pattern: ˆerrno: <#.number> - <*.error_text> will
match a message of the format: errno: 125 - device does not exist and
assigns 125 to the parameter number and the message device does not
exist to the parameter error_text.
Variable names may only contain alphanumeric characters as well as
underscores (_) and hyphens (-). The following syntax rules apply:
(Letter | '_'){ Letter | Digit | '_' | '-' }
In the syntax above, Letter allows letters and ideographic characters
from all alphabets, and Digit allows digit characters from all alphabets.
