I am writing an application that requires a number of text icons to be
updated fairly regularly (frequency definable by the user). Currently, I
am using the SWI SetIconState with zero arguments to force an update, but
if the update frequency is more than a few frames per second, the flicker
is quite intolerable with or without icon borders. I have also tried the
SWIs ForceRedrawWindow and UpdateWindow (names may be slightly wrong), but
this does not improve things. My question is, is it possible to use the old
GCOL type tricks by EORing text into the Icon? If so, how is this done ?
If not, will updating the Icon as a Sprite help ?

Any other hints on how I could rid myself of this annoying flicker would be
greatly appreciated.

I am sure that all this information is in the PRMs, but I am reluctant to get
a copy until the RO3 version is available (I have an A5000).
I am sort of hoping that if will be available for the Acorn User Show (which
fortunately coincides with my next visit to England :-)). Is this a real
possibility, or am I living in dream world ?
