@Adám the only thing I just noticed is that you put # instead of £. I'll have to actually try it out later.

seems to be working though

@Adám does MSKLC's "Print" feature work for you?

@MartinEnder Thanks. I'll have a look.

@Adám what does # stands for?

@MartinEnder Also, the NOT symbol is on Shift+Tilde, and "/@ are swapped. Besides, I've added BrokenStile and NOT to both US and UK.

@Uriel # is the root namespace (in the workspace). Do you know about OO?

@Adám yup

@Uriel So, Dyalog APL has two basic object models: the namespace and the class. The class is basically identical to the OO of Java and C#, while the namespaces provide simple containers for items.

@Adám so the root namespace is like the global scope in C and C#?

@Uriel I don't think so (I don't know C or C#). The root namespace contains everything else (almost) in a tree structure of namespaces (classes and instances are also namespaces), but things in # are not directly available from sub-namespaces without an explicit reference to #. I'll make an example for you…

@Adám thanks! I think I got it pretty much.

@Uriel Good. Let me know if anything is unclear. Main thing to note is that Dyalog APL uses the dot syntax for spaces: parent.child, the root is #, and the reference to the parent is ##. E.g. #.myspace.##.var is the same as #.var.
