rep vs forstr s ss="one[]two[][]four[]"

[ken gray]

in the help file for getl you use the following code to get each line of a var.

Code:

Copy      Help

str s ss="one[]two[][]four[]"
int i
for i 0 2000000000
    if(s.getl(ss -i)<0) break ;;no more
    if(s.len=0) continue ;;skip empty
    out s

i noticed the rep also works.

Code:

Copy      Help

str s ss="one[]two[][]four[]"
rep
    if(s.getl(ss)<0) break ;;no more
    if(s.len=0) continue ;;skip empty
    out s

would it be better to use rep since you dont need the extra var and you dont have to calc or does "for" run better in an intrinsic way?

thanks
