Hi Xav, something in preparation ????

Try to put on paper what you want your program to do.
So you will know when you have to initialize variables or perform a test upon values, jump to a specific section of your code (subroutine)...

But first of all, follow the ZX81 manual and its exercices, it is very didactic.

Here a simple example :

Hello, the program can not run properly as is. Did you try to run it yourself ?
Try first to write the algorithm of your program, you will see that the listing you made has many errors.
Keep trying but read the manual and tape in some other programs, it will help you understand yours errors.

Hello, do you find this +3 on ebay last week ?
I saw one for sale and on the pictures on the +3 it was wet with a few bubbles .
Clearly the seller made a quick cleaning with a kind of soap and water or something like this...
(I did"nt bid on the +3 after that)

Hope it will be ok once dry !

Great ! You save me from a long typing night !
It works well

Hello Graham, you will have a lot to catch up

By the way i was once looking for High Rise Hive but never typed (it was in Your Computer in 1984 if i remember well), il will have to find it.

Hello, i'll PM you

Hello Crayon, your programm can't work properly anyway, it is not a problem of amount of memory :| I think you should take a look at the programing manual so you could use correctly variables, input command or conditions (IF, THEN....). Here is an online manual http://www.worldofspectrum.org/ZX81Bas...

Hi, seems that the file is missing

Hello
what to say after that ? They said (and they know !) much more than i am able to

So just the essential for me, welcome on board !
