Re: STEPS - New 16K ZX81 Game

Cheers to Bob, it looks right at home on the ZX81 screen

And cheers to the original designer Ahmed. As a game it is difficult, but I work at it a few minutes every week and have progressed a bit. I'm still not sure what each icon represents yet sure it will become more clear in time

Re: [type-ins] "Ordi-5" french programs.

Very nice. I examined the keyboard article "Change the meaning of the keys on your keyboard" -- it was very informative. I transcribed the original text of the article. Can it be added to the type-in files?

Re: New release of EightyOne available

Is working well

Are there any plans to fully support file names with a space in the name?

Re: Hi All

Welcome!

Does the Spectrum have 64K memory? It sounds like a great home computer. Our ZX81 has maximum of 48K but only a portion of that can be used for code

Re: Taxmate: First and final release

ROUND(num,2) to two digits to show the cents

unfortunately Sinclair BASIC doesn't have a ROUND command


perhaps use Something like

Code: Select all

   LET Y=(I)+SIN (U)-8.25
   LET Y=INT(Y*100)/100
   PRINT Y
Taxmate may have a bug, the utilities tax are almost as much as the income tax
