New in next thinBasic: FOR with on-the-fly variable definition

[Petr Schreiber]

Zlatko,

if you are puzzled by NEXTs lacking specified variables, you can still add simple comments there:
[code=thinbasic]
for X as long = 1 to 16
for Y as long = 1 to 16
printat format$(x*y, "000"), X*4, Y, 14
next 'Y
next 'X
[/code]

It is just one character extra, and it means no hurt to parsing performance, as ThinBasic cuts the comments before execution.


Bye,
Petr

Hi guys interesting stuff but i prefer this:
for X as long = 1 to 16
for Y as long = 1 to 16
printat format$(x*y, "000"), X*4, Y, 14
next Y
next X
it is easy to track...

I must admit that I don't understand the need for having the variable following 'next'. It seems to me that for now a work around could be:

for X as long = 1 to 16
for Y as long = 1 to 16
printat format$(x*y, "000"), X*4, Y, 14
next ' Y
next ' X

By commenting out the variable, thinbasic can still handle the for/next loops and by having the variables there as comments it still remains clear.
Just my thoughts on the subject.

Thanks

OK, done.

Next thinBasic version will manage both syntax without speed reduction.
thinBasic will allow the Counter variable after NEXT keyword but it will be ignored and parsing will jump over the next token.

There will be no execution speed reduction because there will be a check of the presence of Counter variable after NEXT keyword during Script-Pre-Parsing phase. During this phase, if parser will find some NEXT followed by looper variable, they will be "marked" so real execution will just ignore the next tokens and jump to the exd of line.

Ciao

I don't think you did anything wrong! I hope you didn't get any ideas from what I said that could have made you think you did anything wrong. I believe that any suggestions can and should be made. Please feel free to make any suggestions you have.

Thanks
Sandy
