Repeat Loop

[MrXuj]

Hi there everyone,

I was playing with some code and I ended up with two pieces of code in a program.
Both were part of a Repeat loop. So I wanted to try something out. It works so far, however, I don't know whether this will mess things up later on.

What I have, not the actual code, but a simple rendition of it:


If not(Ans
Repeat A=B
If 0<Ans
Repeat A=C
End


Is this an effective way to do something that's written the same way, in two loops? Or would this bring errors?

This is actually not a good idea. It will screw up the Basic parser if it tries to skip over this bit of code, because the number of Repeats and Ends don't match.

Ah, I see. Well back to typing again then. Thanks for the answer.

The BASIC parser can be strange (or fun, if that's what you think) like that. One of my favorite examples: (this is not an original idea, I am sure that this has been mentioned elsewhere)

Repeat A=Bnot(Ans)+C(0<Ans

Again, a simple rendition, as Ans will likely need to be preserved better.

Should Ans always remain in the positives:

Repeat A=Bnot(Ans)+Cnot(not(Ans

or

Repeat A=C+(B-C)not(Ans

The two being of equal size, we should now test which one is faster:

startTmr→T
For(X,0,1)
For(A,0,16)
For(B,0,16)
For(C,0,16)
X
expr
End
End
End
End
checkTmr(T

expr = A=Bnot(Ans)+Cnot(not(Ans
116 seconds

expr = A=C+(B-C)not(Ans
121 seconds
