How to access user-defined service variables in a command object

[Paul M. Dubuc]

Sorry to have bothered the list.  I was making the problem too hard because I 
was confused by what I'd read about on demand macros in Barth's book (p. 632). 
  Using $_SERVICE_ALARM_NUMBER$ works in the command definition.  I don't know 
why I didn't try that first.  For some reason I thought you had to specify the 
host and service description to get the value of the variable.
