variable={"ABCDEFGHIJKLMNOPQRSTUVWXYZ"} puts(1,variable[8,12,16,20]) --is the same as puts(1,{variable[8],variable[12],variable[16],variable[20]}) just an idea, real easy to implement I think even allow ? variable[8,12,16,20..26] or more complex subscriptings --same as ? {variable[8],variable[12],variable[16],variable[20..26]} use if for swizzled assigns as well, man I would really love this variable[1,5,9,13]={1,2,3,4} --same as variable[1]=1 variable[5]=2 variable[9]=3 variable[13]=4 much cleaner code, I like it

Another that comes immediately to mind is {a,b,c,d}=s[1,2,3,4] which would be the same as a=s[1] b=s[2] c=s[3] d=s[4] The reason for this is because sometimes you need to go back and forth between using a sequence and using 'named' variables. As (i think) you already said: s[1,2,3,4]={a,b,c,d} would be nice too, to go the other way. And as you said with the printf statement, that would be nice where any set of values is expected (i guess you meant that too). Gee ya know, with ideas like these this "Euphoria" may turn out to be a real language someday :) Take care, Al And, good luck with your Euphoria programming!

Perhaps to remind it can enforce the request. An expression like:
newString = originalString[1..2]&"INSERT"&originalString[5..9]&originalString[27..$]
could simply become:
newString = originalString[1..2]&"INSERT"&[5..9]&[27..$]
It should be plain to implement, I mean more useful than complicated... antonio

I don't think that would work very well. What if you wanted to use multiple strings like:
newString = originalString[1..2] & "INSERT" & otherString[3..5] & [5..9]
What would the "[5..9]" refer to? I like the idea of listed subscripts though. It would only be useful IMHO if it worked with predefined sequences like:
constant REPORT_FIELDS = {1,5,9,13} sequence item --in some for loop item = record[REPORT_FIELDS]
That changes the semantics codepilot originally brought up though, ie: variable[1,5,9,13] does not look the same as variable[{1,5,8,13}] and Al Getz wrote: > I've had my share of problems like this too, where you could use > some sort of functionality to deal with sequences easier. > Another that comes immediately to mind is > {a,b,c,d}=s[1,2,3,4] I think Rob has already made his views clear on multiple lvalue assignment and I tend to think it would be a headache in the context of Euphoria. What happens (even in the case of a subscript list) if the sequence s is not as long as the subscript list? Gary

Hi Gary, The last declared sequence, of course. I don't see where the problem arises. If I had put to you the same question, which could have been you answer? antonio
