Bit ugly, but I see the logic. I still maintain it's a fail on the part of those bits of software, though

In fact the lexer does not know what is Assembler and what is BASIC. Standard lexers can recognise only one syntax, and ZX BASIC has two types of REM characters, which confuse ANY lexer. So the only solution is to use this sequenze in ASM.
Talking about it: ASM command SUB opens also a fold point in BorIDE, so I'm not a fan of using same keywords for BASIC as they are used by Assembler. Instead of SUB I would use PROCEDURE or PROC.
