Here's something I wrote a few weeks back (not on hardhats) that might
be helpful:
As you probably know, the parameter tool is designed to manage a set of
key/value pairs very much like the Windows registry. The key point is
that the same key may be defined at various levels of granularity:
"USR" (user), "CLS" (class), "LOC" (location), "SRV" (service), "DIV"
(division), “SYS” (system), “PKG” (package), and more. The key point
(no pun intended...well, maybe a little) is that a given key can be
associated with different types of granularity (called “entities” in
the parameter tool documentation), and when retrieving a parameter
value, you needn’t specify the particuar entity in which you are
interested. In fact, a common use case is searching through a list
(e.g., “USR^CLS^PKG”) or through all of them, looking for the first
“hit”. Now, why might this be useful? Imagine a parameter that contains
the location of a laboratory. Most physicians may wish to use th
nearest laboratory (a hit under “LOC”), but maybe there is no
laboratory associated with their location and they need a default. It’s
also possible that a physician may practice a specialty where not just
any laboratory will do, but instead they may need to use a laboratory
that has more specialized equipment, even if it isn’t the closest.
Now, one thing that can be confusing about the parameter tool is that
some entity types need to be qualified and some do not. For example, I
have used “USR” level parameterts to allow users to specify where they
want certain host files saved (or retrieved). Different users have
different default directories under VMS, and so they want to get
different answers when asking for a directory to use. Accordingly, in
the generic query (CSLQQ) you find the following
S UDIR=$$GET^XPAR("USR","CSL QUERY DEFINITION DIR")
But how does the parameter tool know which user is invoking this code?
The obvious answer is that it looks at DUZ. But what if I wanted a
value associatd with a location? That’s harder because there is no
convenient variable to check. The answer is that “LOC” needs to be
qualified in the call using “LOC.somewhere” instead of just “LOC”. The
following code, kindly supplied by Kevin Meldrum, shows how a value
might be qualified at runtime by setting LOC to the SERVICE/SECTION
pulled from file 200 and appending the internal value to “SRV”. (The
entity “LOC” is used to refer to entires in the HOSPITAL LOCATION file
(#44). I realize I’m kind of confusing things by switching from “LOC”
to “SRV”. Sorry about that.)
S LOC=+$G(LOC)_";SC(" I 'LOC S LOC=""
S ANENT="ALL^"_LOC_$S($G(^VA(200,DUZ,5)):"^SRV.`"_+$G(^(5)),1:"")
S MNU=$$GET^XPAR(ANENT,"ORWDX WRITE ORDERS LIST",1,"I") Q:'MNU
I believe it is possible to use a .01 value here, but a pointer may be
used as “`253” or (in variable pointer syntax) “253;SC(“.
Generally “PKG” is the “value of last resort”, that is, the least
specific value you may wish to associate with a key. System, or “SYS”
is one step down from that, giving a value that applies to anyone using
the parameter at a given facility (unless something more specific
matches, instead).
Clear as mud?
