What is the equivalent to )SI ?

[PGilbert]

Is it possible to get the equivalent of )SI as a system function or by code ? ⎕SI and ⎕XSI are missing the line numbers. This could be use to store the state indicator into a file when there is a bug happening in the application. Without the line numbers ⎕SI and ⎕XSI are not very useful for that purpose.

Thanks,

⎕LC gives the line numbers, so ↓⍉↑⎕SI ⎕LC gives a vector of function-line_number pairs.

Thanks John for your reply. Here is with your help what I was looking for:

      ⊃⎕XSI{⍺,'[',(⍕⍵),']'}¨⎕LC

Is this a 'safe' expression that will never bug ? Is ⎕LC will always have the same dimension as ⎕XSI ? Would it be possible to add the thread ID of each interrupted functions somewhere ?

Yes. ⎕SI and ⎕XSI were designed to be the same length as ⎕LC.

Would it be possible to add the thread ID of each interrupted functions somewhere ?

I can't think of a way to do this.

Thanks John for your time.

Careful, though: ⎕SI/⎕XSI provide data only for the thread they are executed in, whereas )SI shows the stack for all of the running (or paused) threads. As far as I know, there is simply no way, to rebuild the result of )SI in code.
