How works?

Thanks' Gaslouk

Ah, simple....

FOR
[IF [NOT(] condition [)] THEN EXIT FOR]
code
[IF [NOT(] condition [)] THEN EXIT FOR]
NEXT

WHILE [NOT(] condition [)]
[IF [NOT(] condition [)] THEN EXIT WHILE]
code
[IF [NOT(] condition [)] THEN EXIT WHILE]
WEND

DO [[WHILE] [UNTIL] condition]
code
LOOP [[WHILE] [UNTIL] condition]

Not sure you would ever need EXIT DO or if it exists. The trick is to focus on the code and choose the loop that gives the cleanest execution or non execution of the code within the loop. So do you want it done once then check or check before you do it. choosing the correct loop can avoid the need for EXIT code. DO LOOP is probably the most flexible structure and the least used!

Yes it does exist
I use it regularly as in

inStr$="Hello there again!"
do while 1
   i=i+1
   w$=word$(inStr$, i)
   if w$="" then exit do
   print i, w$
loop


[Rod]

inStr$="Hello there again!”
i=1
w$=word$(inStr$,i)
do while w$<>””
print i, w$
i=i+1
w$=word$(inStr$,i)
loop

No exit code but some set up.

There is more then one way to skin a cat.
But having a choice is better then not having it.
