HP-71B IMAGE and PRINT USING

[rprosperi]

I suspect the problem is this: "'&CHR$(248)&'" which is intended to insert the degree symbol.

As written, it would seem to be trying to treat the entire '&CHR$(248)&' as a literal string, when I think you are simply trying to append CHR$(248).

Also, consider using the "B" Special Output Symbol - it may be easier to use in this complex image string.
