Re: generate an Array using value for naming the keys?
Thanks for this also. I will keep that in mind, but for now i will use the &
syntax.
Format() is also a function i often struggle with. ;)

RE: generate an Array using value for naming the keys?
Mark,
I will start doing this. I have a headache just thinking of the last time I
had some complex keys and trying to read the code with the afore mentioned
quotes and ampersands. Learn something new every day.

No problem - of course, I used & in my example - but when I'm doing stuff
like that I tend to use format:
put tFoo[format("wp_%s_%s", tMiddlePart, tSuffix)] into
tMiddlePartSuffixValue
It does the same job, but I find it more readable (as the structure of the
string can be seen immediately without having to wade through quotes and
ampersands :)
Warmest Regards,
Mark.

Mark, thank you very much! i didn't know or remember that the key name of an array can be created directly using strings and variables Maybe i even did that in the past, but could not remember anymore. I really thought i have solved it that time with value() :) Regards, Matthias > Am 11.05.2023 um 16:36 schrieb Mark Waddingham via use-livecode > : > > On 2023-05-11 14:36, matthias rebbe via use-livecode wrote: >> The middle part of the key names changes and there can be about 50 different >> "middle parts" and there are 10 main keys (after the middle part) >> _content, _text _html and so on. >> So without an idea i would have to create the code to fill all values for >> the array keys with the middle part aa and then the code for the middle >> part cd and so on. >> Is there a way to use value for this.

Perhaps I'm misunderstanding what you are trying to do as you mention using value() for something which doesn't sound like it needs it... Array keys can be arbitrary (string-valued) expressions - i.e. they don't have to be literal strings: e.g. put tFoo["wp_" & tMiddlePart & "_" & tSuffix] into tMiddlePartSuffixValue Warmest Regards, Mark. -- Mark Waddingham ~ m...@livecode.com ~ http://www.livecode.com/ LiveCode: Build Amazing Things ___ use-livecode mailing list use-livecode@lists.runrev.com Please visit this url to subscribe, unsubscribe and manage your subscription preferences: http://lists.runrev.com/mailman/listinfo/use-livecode
generate an Array using value for naming the keys?
Hi, once in a while i am struggling with value(). ;) I have the following problem. I need to create an array which keys are something like this wp_aa_old wp_cd_old wp_ek_old wp_aa_new wp_cd_new and so on. The middle part of the key names changes and there can be about 50 different "middle parts" and there are 10 main keys (after the middle part) _content, _text _html and so on. So without an idea i would have to create the code to fill all values for the array keys with the middle part aa and then the code for the middle part cd and so on. Is there a way to use value for this. So i could just add the middle part of the key name to a variable and use that then with value() to create and file the array? I think i have done this before, but i might be wrong.
