Hi,
just an experiment to see what can be done ... Works like a charm - mostly :-) ⍝ ------------------- an arbitrary function. ∇example[⎕] ∇ [0] Z←example name_struct [1] Z← name_struct [2] Z.N ← 'new' [3] ⎕EX 'Z.K' ∇ ⍝ ----------------- some data A.B.C.D ← 14 A.B.C.K ← 20 ⍝ ---------------- content of a A .B: .B.C: .B.C.D: 14 .B.C.K: 20 ⍝ ----------------- experiment example A.B.C 1 ⍝ ⎕EX ⍝ returned by Z: .D: 14 .N: ┌→──┐ ⍝ line [2] │new│ └───┘ ⍝ ----------------- even this can be done V ← example A.B.C 1 ⍝ ⎕EX V ≡ example A.B.C 1 ⍝ ⎕EX 1 ⍝ ≡ ⍝ ---------------- here comes the bug: ∇example[⎕]∇ ∇ [0] Z←example name_struct [1] Z← name_struct [2] Z.N ←'new' [3] ⎕EX 'Z.K' [4] Z.K ← 'NEW' ⍝ added line [4] example A.B.C 1 ⍝ ⎕EX SYNTAX ERROR example[3] Z.K←'NEW' ^ Z.K←'NEW' ⍝ does it immediately after syntax error →3 ⍝ repeat from ⎕EX on 1 ⍝ ⎕EX ⍝ returned by Z: .D: 14 .K: ┌→──┐ │NEW│ └───┘ .N: ┌→──┐ │new│ └───┘ Best Regards Hans-Peter
