Getting Names in Namespace in Order of Assignment

[paulmansour]

⎕Nl returns things in alphabetical order.

Is there any way to retrieve the the names in a namespace in the order in which they were assigned?

If not, internally, how are the names in the symbol table stored? I would hazard a guess they are stored in some sort order related to assignment.

I'm afraid not .. the names are held in a binary tree, in the same order that Grade uses, so is different in Unicode and Classic editions.

Ok, thanks Andy.

I'm trying to impose order on the names in a namespace (for presentation, not computation). Order of assignment is usually how I want it. By hook and crook I can determine that order most of the time, but there are times when can't. I guess I will have to settle for explicitly assigning the ordering.

There isn't a way to report this after the fact, but if you are sufficiently keen, in v16.0 you can roll your own solution using the extended Trigger mechanism which is designed for implementing various forms of data binding:

Code: Select all

      NS←⎕NS ''
      NS.⎕FX'LogAssignments arg' ':Implements Trigger *' '⎕←arg.Name'
      NS.life←42
life

Thank you for the hint. That is really cool!

That Seems to be mentioned now as "Global Triggers" in the most recent version of the Programming Reference Guide, dated Aug. 10th., to be found on the web site.
