Re: [Bug-apl] ⎕ES wrong message

[Elias Mårtenson]

Jürgen,

Do you think it would be possible to implement some way of retrieving not only the error code, but also the )MORE text from an exception inside an ⎕EA?

The reason for this is that in my SQL∆WithTransaction call, I need to call the rollback function if there is an error, but then I want to ensure that the original error gets thrown. For SQL this is particularly important because the SQL error report is embedded in the )MORE message.

Regards,

Elias

Hi Blake,

I believe the ⎕ES related bugs reported recently should be fixed in SVN 372.

This one is not, though. The reason is that fixing it would have considerable performance
impacts (we would need a copy of every defined function argument only for the rare case that ⎕ES
is called),

I also find it somewhat arbitrary to show a non-locked function as locked in this very specific case.

Since ⎕ES is not ISO-standard anyhow, I take the freedom to trade performance for APL2 compatibility.

⎕ES is showing the modified and not the original argument passed to the function.  IBM APL 2 displays the original argument passed.

Thanks.
