Paul, I tried the new (April 6 2021) release 8.71 compiler on a few programs. I am pleased to note that several of the bugs that I had reported have been fixed in this release, and it generates 64-bit EXEs that perform quite well.
I noticed one regression, however: compiling a source and asking for a cross-reference listing with the /XREF option produces a listing of the variables, but the listing contains no line numbers!
