parsing speed

Hi everyone,
I have a question on parsing speed.
I have two functions:
F1
F2
As things are now, F2 calls F1 internally:
F2 = function(x){
if (something == 1){
y = F1(x)
}
if (something ==2){
do whatever
}
}
*Assuming there could be some difference*, is is faster to use the code
as written above or should I actually write the statements of F1 to make
the parsing faster?
The parsing only happens once when you define the functions, and is (almost always) a negligible part of total execution time. I think you're really worried about execution time. You'll probably get more execution time with a separate function because function calls take time. However, my guess is that putting F1 inline won't make enough difference to notice. Duncan
