This typed from memory (late 40s and is starting to haze). Program will
probably run as is on a TRSDOS Model III and IV - not on cassette based
BASIC... and as noted by Chris Osborn, the CoCo ECB won't handle more than
one variable on the DEF FN statement *despite* the ECB manual calling for
'variables' on the review of it, plural but not quite - the simple DEF FN
examples on that book only show a one variable defined function. Better off
writing the thing as a subroutine in ECB.
