Compiling pure Sinclair Basic

[Jodo]

Hi,
As per the subject, I'm trying to compile pure Sinclair Basic but am getting the following errors which I can't find anything about.

bwall.bas:4: Error: invalid directive #Run
bwall.bas:4: Error: illegal preprocessor character '-'

bwall.bas:68: Error: invalid directive #End
bwall.bas:68: Error: illegal preprocessor character '-'

I used this command: 'zxb bwall.bas --tzx --BASIC --autorun --sinclair --explicit' to compile
but have also tried without '--sinclair' and '--explicit' with the same results.

If anybody has any ideas I would be really appreciative. Thanks.
