I'll point out that if using f. is critical then you might as well have: newverb =: (3 : ' 0 0$WRITENIF=:WRITENIF,,y')@(2&ic) writenif
You rarely gain any maintainability benefits by ensuring that your verb_base_ will get updated if you improve 'put'. If you want the maintainability advantage of the new verb reflecting future improvements, don't use f. Also, you probably know that , when you use f. you in fact will not get improvements if you reload the other locale file without reloading the base file. So, an error can go undetected until you reopen the whole project. Using f. accross locales this way will make you paranoid with reloading and rechecking verifications with abnormal frequency. ----- Original Message ----- From: Raul Miller <[email protected]> To: Programming forum <[email protected]> Cc: Sent: Tuesday, February 18, 2014 7:18:48 PM Subject: Re: [Jprogramming] wat? (seems like a spurious value error from f.) But that would mean that I am storing variables in the wrong locale and defeats the point of using separate locales in the first place. I will use a workaround, but I would like to understand what has gone wrong here. Here's how to reproduce: cocurrent 'writenif' put=: 3 : ' 0 0$WRITENIF=:WRITENIF,,y' ic=: 3!:4 write_int=: put@(2&ic) cocurrent 'base' write_int_writenif_ f. |value error: put Thanks, -- Raul On Tue, Feb 18, 2014 at 5:18 PM, Vijay Lulla <[email protected]> wrote: > Looking at definition of 18!:2 it states "If a name sought in locale f is > not found in f , then it is sought in the locales in the path of f (but not > searching *their* paths)."
