I was using Ro 4.39 on the RiscPC, so it seems that version has the 
required clipboard support.

I'll have to revisit that version of my script (which was written for 
me by Julian Fry) to see how he did it.  Ah: his script calls a little 
Basic prog that uses   SYS "Clipboardholder_copy",0,&FFF,A%,L%   
(where the arguments A$ and L% are set by previous lines, but I dunno 
wht the 0 and &FFF are).

Your assembler in the file !Minitime.Source.Taskpart uses SWI &6E000 
for Clipboard_put, if I understand aright.  So could I adapt Julian's 
Ro4 routine to use  "Clipboard_put"  by name rather than SWI number?  
Can't find any specs for it in the Stronghelp manuals supplied with 
ArmX6 that cover a lot of other SWIs.

I'm confused.  Are you saying this clipboard module (or at any rate, 
functionality) is or is not there within the Ro 5.23 that I have on 
this ArmX6 and 5.22 on the Armini?  I take it that if Minitime is to 
work, it must be there.

I must admit that the Rool powers-that-be sometimes come across as 
somewhat aloof (shall we say) in verdicts of denial.  (Recognizing 
that we're all volunteers in the RiscOS world, let's be gentle.)
