IMO whatever is the easiest to write and read that gets the job done is 
the best option.


The first example above seems simplest to me.

The second one isn't bad, but the third one should be avoided unless you 
have something in the data that requires the overhead of adding a call 
to the value function.

Re: Value & parentheses when doing math

[Bob Sneidar via use-livecode]

The second one is more readable. The third is unnecessary. The first works just 
fine. It just depends on how readable you want to make your code for others. I 
always take the time to put values into their own variables so I can point at 
them in the debugger and see their current values in the stepper. So:

put item 4 of line x of tList into tValue
add tValue to tRunningTotal

seems to me to be more readable, at the expense of a little extra typing.

Value & parentheses when doing math

[Knapp Martin via use-livecode]

I have a tab delimited list where item 4 is a number and I'm adding things up. 
What is considered best practice when doing this?

add item 4 of line x of tList to tRunningTotal
or
add (item 4 of line x of tList) to tRunningTotal
or
add value(item 4 of line x of tList) to tRunningTotal
