⎕NA domain Error
Hi
I am happily using a call via ⎕NA to define "ps" as "winmm" (to play ".WAV" files) via:
However if I try to define "#.ps" rather than "ps" I get a Domain Error thus:
I was surprised by this Domain Error, but got round it easily, so it is not an actual problem for me.
Is this Domain Error correct, or should I be able to define "#.ps"?

Re: ⎕NA domain Error
Hi Ray,
I have logged this as an issue, 21425.
One could argue that we should allow a namespace qualified name as the left argument of ⎕NA.
I will leave it to the developers to decide whether to implement that or document this restriction.

Vince

You don't detail how you go around it, but I imagine that this will work:
'ps'#.⎕NA'Winmm.dll|mciSendStringW <0t >0t i U'
