How to *completely* stop a script after stop()?

Hi Carl,
If you wrap the whole script in brackets the script will not proceed
past the stop() function:

{
for(i in 1:10){

        print(i)
        if(i == 5) stop("i == 5")


}
for(i in 11:100) print(i)
}

best,
Ista

Somehow this reminds me of a famous FORTRAN code snippet:

10 STOP
STOP
STOP
! IN CASE STILL SKIDDING
GOTO 10

Dear expeRts,

is there a neat way to *completely* stop a script after an error occured?
For example, consider the following script:

## ==== file.R ====

for(i in 1:10){

        print(i)
        if(i == 5) stop("i == 5")


}
for(i in 11:100) print(i)

## ================


stop() behaves like it should namely to stop the execution of the *current*
expression, but I was wondering if it is possible to *really* stop the
script after the first for loop [so without executing the second for loop or
anything after that point]. Of course one could use something like "if(there
was an error) do not continue" but that's not really nice.
