The repeat statement

[Sidharta]

There are a lot of times we use a loop just to repeat a finite number of times
It would be usefull to have a new loop statement like this


sub procedure
repeat 8

' everything we want to do 8 times


end repeat



end sub

sometimes is clearer than the rest of loops

[anton]

sub procedure
repeat 8

' everything we want to do 8 times


end repeat



end sub

Then it won't be Basic anymore

[Steve]

That's exactly what the for loop is for.

[xor]

The FOR-NEXT loop permits use of variables for start and stop points which is important to some applications.

[Sidharta]

I think repeat allows to avoid using a variable .
Probably in assembler it allows a more efficient code.
You don't have to worry about limits in the for loop
Of course it's possible to live without it

[Steve]

You will still need a variable to keep track of the number of times you wish to repeat the loop.

It would be redundant to have two constructs that do the exact same thing.

[xor]

For-Next is a very flexible type of loop that also does simple Repeat.

Code: Select all

FOR a = b TO c 
    'Some more code
NEXT a

Also:

Code: Select all

FOR a = b TO c STEP d
    'Some code
NEXT a

b is the start variable value and c is the stop variable value (no redundancy here). Using variables instead of constants allows for a flexible Repeat sequence and saves on code size.
