It is possible for non-BASIC programs to call subroutines in the BASIC
ROMs directly to their addresses. The Vertex "OEM IBM ONLY" edition of
Xeno-Copy, which was supposed to never be released, but was used by
PC-WORLD in a January 1983? comparison of compatibles.
All early versions of XenoCopy would run on an 8088, but not 8086 or
above, due to my failure to prepare for a change in the size of the
pre-fetch buffer.
I will accept the title of "pedantic". There DO exit exceptions, just not
any that matter.
