Question

I can append a string with number.

temp:30
text:"Current temperature is ",string temp
show text
type text

Result

"Current temperature is 30"
10h

However, if I append one more string, it becomes a list. (why?)

text:"Current temperature is ",string temp," degree celsius"
show text
type text

Result

C
u
r
r
e
n
t
 
t
e
m
p
e
r
a
t
u
r
e
 
i
s
..
0h

I can use sv with empty string as delimiter, is it the normal way to do it?

text:"" sv ("Current temperature is ";string temp;" degree celsius")

Answer 1

comma operator treats each character in the concatenated string as a separate item and creates a list of those characters.

On the other hand, when you use sv with an empty string as the delimiter, it joins all the strings in the list into a single string, which is the desired behavior for concatenation.
