fwrite bug

Hi,
the file function fwrite, fail to write without errors (return 0) if the variable string is flash saved

this write 1024 bytes to file

dim buff$[1024]
function ttt()
dim ln,fp,error
    fp=fopen("test.bin","w")
    error=fwrite(buff$,1024,?ln,fp)
    fclose(fp)
    return
endf

dim buff$[1024]

flsave("")

this write 0 bytes to file without error

function ttt()
dim ln,fp,error
    fp=fopen("test.bin","w")
    error=fwrite(buff$,1024,?ln,fp)
    fclose(fp)
    return
endf

And more, may be usefull to have a function that write from a string pointer instead of a string variable
example...

fwrite(?buff$+4,1024,?ln,fp)

Please fix it as soon as possible :)-D

The bug here is that the string looses its size in the first 4 bytes when saved to flash. To be fixed in the next release. A workround is to put the size back on reset thus:

poke(buff$,1024)

There is still a problem with the sizing of strings on version 69 so the global save needs looking at.

many thanks Jim
