#ObjectScript

This morning on the old Caché Google Group, someone posed the following question, which I've decided to answer here, because it's interesting!

Is there a way to iterate ClassMethod's params, and get param's names and values?

The first answer I can come up with is: it's not easy! In any method, you could try to write code like this (where methodName is the name of your method):

    set method = ##class(%Dictionary.MethodDefinition).IDKEYOpen($classname(), methodName)
    set args = method.

Looking at a property defined as follows:

Property SystemTime As %Library.TimeStamp [ SqlComputeCode = {Set {*}=$ZDATETIME($NOW(),3,1,0)}, SqlComputed ];

The documentation talks about using SqlComputed and SqlComputeCode with SqlComputeOnChange (specifying which events will trigger computation), and about using them with the Calculated keyword (so it's always computed). I don't see any specific explanation of the case above, though, when neither SqlComputeOnChange nor Calculated is specified.

I've searched the ObjectScript reference for any instances of Upper, Lower or Case and the only thing is a case/switch statement.  In all the documentation I can only find SQL and Cache Basic references for things like UCASE.

So how do I do this in ObjectScript?

For instance,  if (ucase(dtype)="G") { }
