ClassMethod with global parameter undefined when attempting to Order
I have a class method that accepts a global parameter but when I attempt to order this global, the global name is listed as undefined. I can execute $DATA(pGlobalName) successfully.
ClassMethod ExamineGlobal(pGlobalName As %Global) {
set gStatus=$DATA( pGlobalName
) ; returns 1 write "This is the global name: "_pGlobalName
set gmin=$ORDER( pGlobalName
("")) ; here pGlobalName is undefined}
In debug mode, data returns 1 for a valid global with no descendants. This is expected.
However, when I call $ORDER, it shows <UNDEFINED> for pGlobalName. My guess is that ORDER is operating on the local variable pGlobalName instead of its value? How can I 'dereference' the variable name so that the Order method operates on its value rather than the name itself?
I want to use this for an array of seventy globals and would rather have o single method call to perform work for each global rather than having to explicitly write code for every global.
Thank you.
I should mention that I am using Cache Ensemble 2010.
