Re: [Bug-apl] Localizing ⎕CT

[Juergen Sauermann]

Hi Jay,

I see, thanks. I believe both methods (keeping the current value or using a default value)
are reasonable approaches. My primary goal was to have some reasonable value
for all ⎕-variables, so that I can avoid tests all over the place (in particular for ⎕IO and ⎕CT).

I would also say that a well-written APL program should not make use of this "feature".

To avoid incompatibilities with existing GNU APL programs, I believe I should not
touch the current behavior.

FYI this is different from NARS2000 and Dyalog, which leave
⎕-variables set to their current value, rather than setting them to
some default value.

to their default values when they are being localized.
