Right, I know this one
Maxam 1.5 FTFW. Best assembler the CPC ever had, unless you asked the French, who all used DAMS. And some people used Roland Waddilove's RAW Assembler, which was a type-in in CWTA, because it was free.

I'm about the only person who still uses hard tabs in any open source project I contribute to, and the sole reason for that is that I learned to program on an Amstrad with 40k space for source code, and a hard tab saved five bytes.

Nope, I still use tabs
but only because I can't STAND repeatedly pressing the space bar.

If only every single text editor and IDE of the last twenty years allowed you to insert a configurable number of spaces using the tab key ...
