Hello!

I was wondering if there was a better way of testing whether a variable was within a range.

So instead of:

OK, I've been at it again. 

FROGGER 50

Changes:

Cool loading screen
Music - Cars by Gary Newman (Get it???)
New BeeperFX sound routines
The original boasted as many UDG as is possible - now there are even more!
Changes to the graphics
re compiled in ZX Basic
Many code tweaks, changes and improvements

keys are 1,9,0 - I couldn't bring myself to change them.

He is a game I made while leaning ZX basic

It has 5 levels of speed and some nice beeper tracks

SNAKE game

On the spectrumcomputing forum we are struggling to compile a frogger basic game with Boriel Compiler.
https://spectrumcomputing.co.uk/forums/v...=21&t=6057
We have made some progress (in .bas file), but the game is still far from fully functional.

Any help would be welcome...

Very quick question,

 could ZXBC target a 128K BIOS ROM in the asm compile routines?

I'm expecting a "no" 

thanks 

Hi
I want to put the code on top memory.
How do I know the length of the compiled code?

Hi

I found that if i dont write a  next in a for the compiler only says "error: Unexpected end of file"

pointing to the LAST LINE  of the program

if i only have a few lines is "easy" to find the error

but if i have 2000 or more lines is a crazy thing to find the error

Can the compiler add a rule to search if every FOR have a NEXT and throw the error  "for without next" ?

This way is more easy to find the error in a BIG program with a lot of lines

You can look the example code



''EXAMPLE CODE WITH EXPLAINED ERROR

dim example as uByte = 0

for example = 0 to 10

    print example

'' THE NEXT MUST GO HERE IN LINE 9 but the compiler logically dont know that
'' BUT Can the compiler say  "error: for without next"
'' instead of "19: error: Unexpected end of file" ?
'' because if we have 2000 or more lines
'' and we dont know what happens
'' is a crazy thing search that error


print "end of program"

After all the hacking questions about the compiler i ended the game and is presented to bytemanicos contest

The game is BASIC FROGGER

Hi

In the original ZX spectrum basic when you PRINT something the variable DF CC is updated with the screen position

for example the next program must print 16384 that is the first position of the screen

but the only answer always with every diferent position is 16448

this means that the print routine is not updating the DF CC variable like the original ROM

Is this a bug?

You can try this program and change the coordinates of the first print 0,0

Since zxbc.py 1.15.3-beta9 the following is causing screen corruption

dzx0Standard(@Pic1, 16384)

Pic1:
asm
incbin "pic1.scr.zx0"
end asm

The same thing happens for text uncompressing.

See attachments for all of the files.

The same code works fine on 1.15.2 stable

Thanks
