Negative STEP does not work (*solved*)

[boriel]

Hi Boriel, I just trying to write some stuff in ZX Basic compiler 1.1.0, but I ran into some problems:

Code:

x=0
if x=1 then
  print "1"
else if x=0 then
  print "0"
end if

I got the message "Unexpected end of file", so if it is a part of FOR NEXT Loop, I got the message "Unexpected Token 'NEXT' <NEXT>". ELSE alone works, but I was sure, ELSE IF should work too, Or maybe I'm wrong?

Hmmm. Every if should be closed with END IF, so another END IF is missing in your code. Try this way:

Code:

x=0
if x=1 then
  print "1"
else
  if x=0 then
     print "0"
   end if
end if

Maybe you were expecting to use ElseIf which has the same syntax you expected. I'll see if I can change the grammar to include it.

Another one: the program does not accept Exponents: 2e4 (=2000) or similar.

Yes, I also find out yesterday. Will be fixed in 1.1.2.

And finally:
Negative STEP does not work with integers or long, only with floats or byte:

Code:

dim x as integer

for x=7 to 1 step -1
  print x
next x

Oops! :? This is very important. I will check this immediately.

The compiler is otherwise fantastic! Please continue your great work!

Thanks a lot for your feedback :!: I will replay when this is Fixed (ASAP).
By the way, version 1.1.1 is out. I suggest you to try it and check if this bug is still there, because I fixed many things.
