Thanks (x10) for that Keith.
So, it's me catching the alt key as I press the space bar.
And then it does not display as EVAL as edit see's it as a hard space. What a great trap I've, once in a blue moon, been falling into there !
I was half hoping someone could explain this 'bug'.
That was the only puzzle remaining for me with using BASIC + EDIT.
Yes, I know Zap and SrongED are both very good (and free) - but not without equally subtle catches for the unaware !
BTW, it's the 'Delete' and 'End' keys that work inconsistantly between Iyonix-Edit and RiscPC-Edit.
(I think some angled brackets around those words in the article fooled the drobe display)
