⎕NA domain Error

[ray]

Hi

I am happily using a call via ⎕NA to define "ps" as "winmm" (to play ".WAV" files) via:

Code: Select all

  
      'ps'⎕NA'Winmm.dll|mciSendStringW <0t >0t i U'  

However if I try to define "#.ps" rather than "ps" I get a Domain Error thus:

Code: Select all

      '#.ps'⎕NA'Winmm.dll|mciSendStringW <0t >0t i U'
DOMAIN ERROR
      '#.ps'⎕NA'Winmm.dll|mciSendStringW <0t >0t i U'
            ∧                  ∧

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"?

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.

Regards,

Vince

Thank you. I will be happy either way.

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'
