Dear all,

I managed to use ChangeFSI in my BASIC program for rescaling a JPEG and
re-typing it to a sprite. The resulting sprite is saved to disk, as a
single sprite file.

However, what I want to achieve is that the resulting sprite is saved to an
existing sprite file that contains more than 60 sprites. It should thereby
overwrite a particular sprite with the same name in that file.

The most likely call seems to be SYS"OS_SpriteOP", but I can't find a
reason code that does exactly that. The reason codes that I tried
nevertheless, either cause a corrupt sprite file or don't do anything
noticeable at all. What should I do? (rather than giving up on trying to be
a programmer).

Kind regards,
Paul
