Subject: [libertybasic] Re: Variable out of loop

Verdict?

I think NEXT is 'Not Guilty'

As Rod has pointed out, it's duty is to increment.
The FOR...TO decides whether to execute the loop.
We decide what should happen in between.

for x=1 to 10
do something
NEXT

Normally the value of x is not important after NEXT.
However, to be safe, we decide to EXIT the loop when x reahes upper limit.

For x=1 to 10
do something
if x=10 then EXIT for
next

Besides other alternatives already mentioned by contributors, the following is easy to understand:

x=0
do
x=x+1
print x
loop until x=10
print x

I still prefer good old FOR...NEXT. There is no need to initialize (x=0) or increment (x=x+1).

Generally speaking, every loop construct has its purpose.

For finite loops, where you exactly know the limits FOR..NEXT is best used.

For loops where you don't know the end limit, but an end condition, you
use WHILE..WEND or DO..LOOP.

Everything can be found in the help file under "Liberty BASIC v4.04 Help
=> Language Syntax and Usage => Logic and Structure => Looping Structures".

If you just read through the help file, you will have a brief knowledge
for what command to use in the current situation.

If you complain that the help file is lacking a search feature, this has
been taking care of already, see http://basic.wikispaces.com/HelpSearch

Thank you Stefan, I found it starts with :
Looping
Liberty BASIC provides three constructions for looping. One is
FOR/NEXT another is WHILE/WEND, and the third is DO LOOP.
I have to study them
very well.
Thanks again Stefan for the link of searching thru html.
