Establishing links between leaves of a tree

[Gabor Greif]

I slightly changed an example from the user manual:

@Diag {
@Tree {
@Circle A
@FirstSub {
@Circle B
@FirstSub @Square C
@NextSub @Square D
}
E:: @NextSub @Circle E
F:: @NextSub @Circle F
}
//
@Link from { E } to { F }
}


This correctly (i.e. without errors) passes lout, but when distilling
the .ps file I get errors:


/tmp/Test.lout.ps:
%%[ Error: undefined; OffendingCommand: E ]%%

Stack:
-mark-


%%[ Flushing: rest of job (to end-of-file) will be ignored ]%%
%%[ Warning: PostScript error. No PDF file produced. ] %%


Looks like the label "E" made its way to the .ps file verbatim.

But, being a newbie loutist, I might gottent the @Link syntax wrong.

Can you offer me some help? Is @Tree capable of linking nodes at tha same level 
at all?

Thanks in advance!
