Problem with Data-Lines

Helo

I have written a small demo programm to show the problem

The expected Output of the program in the simulator uart window should be:

Los gehts...
ABCDEFABCDEFABCDEF
Fertig?

But the Output is following:
Los gehts...
ABCDEF)
Fertig?

The programm breaks by reading the Data lines defined with prefix '$'

Is it a Bug?

Here the Demo code:

Do you read the Help about "Data" statement? I suppose not.

From the Help:

nice example. love that.

the $ is intended to create a string which is terminated by a 0-char by default.
for hex notation you should use &H and in the asm domain you can use $ too.

OK

If the sign '$' is intended to generate a String (&h41 and &h00 in Flash),
then should

Data $41

generate a String with the Char 'A' (ASCII $41) und terminated by char NULL.

Then the output in UART-Window should be

Los gehts...
A
Fertig?

But I get the Output of:

Los gehts...
)
Fertig?

Then you look in (start manual programm) Hex-Window you see generated in Flash at Adress $200 the values: &h00 and &h29. (see attachement!)

And &h29 ist not the same as &h41.

Here the changed Code to check out:

Better hit F1 in the Bascom and type "ASCII chart".
Then you realize that 41 in decimal means ")" and capital "A" uses 65 Wink

BTW. You can always use "Data "A" but there still will be zero at the end.
