| Milestone: | RISC OS disc build complete | Status | Fixed |
Details by Ewen Pring (76):
Change FSI version 1.25 and 1.26 just say “no such mnemomic” when I try to load any graphics file into them. Version 1.21 works.

This is a bug: the assembler code is full of the MRS mnemonics for flag changing; but the opt statements don’t set bit 4, so the extended instruction set isn’t available.
I had intended to submit a fixed version, but the last source I have available is 1.24
It’s moved onto 1.26 in the meantime.

I’ve just submitted an altered version of ChangeFSI which fixes this problem.

It turns out that there are two bugs being discussed here, both of which generate the error “No such mnemomic”
The first one is the one created by Steve in reformatting the source listing, and has been fixed in version 1.27
The second (and the one I’ve been referring to) is caused by a difference in BBC Basic between RO5 and RO4/6
The version of BBC Basic supplied with RO5 will assemble MRS/MSR instructions no matter what bit 4 of the opt setting is.
RO4/6 insist that it be set.
So in conclusion v1.27 will work okay on the Iyonix, and my changes will allow ChangeFSI to work on RO4/6

We have the fix for this in a submissions queue which should be dealt with soon.

James’s fix is now in CVS. Sorry this took so long.
