I have come across a puzzling behavior when trying to use the content of a
field as parametres in a function, and I am trying to understand why.
I put the following in a field called «test»: 1,2,3,4,5
When I then call the function like this:
answer testFunction(field «test»), the paramCount() returns 1
If I use the values directly in the script:
answer testFunction(1,2,3,4,5), the paramCount() returns 5 as
expected
I will also get the expected result if a do the following:
put "answer testFunction(" & field «test» & ")" into tScript
do tScript
I guess the reason for this is that in the last example, LiveCode compiles the
content of the variable tScript before execution, and that this turns what is
first treated as a single block of text into a list of parametres.
The reason why I want to understand what is happening is that I am about to
teach my students how to write reusable code that will behave correctly for any
number of parametres.
So my question is if I am on the right track?
Best regards
Tore Nilsen
