Re: [Gm2] VAR array parameter type compatibility

[SiTex Graphics]

Hi Gaius,

Thanks for these fixes which have enabled more of our main application
to compile.

Any progress on either error displayed by the Cb.mod test I sent
privately?  The 'set element is too  low' error shows up in about 6
other modules, all much more complicated.  The assert failure also
shows up in a couple other modules.  I'm hoping that resolving these
issues might finally allow the full app to build.

Thanks,
Scott
