No because the problem could be recreated using a
simple standalone console program.

It is a bit easier for people that may want to test, than
to get Apache CGI up and running.

Yes, but what about the difference with Pascal?

Pascal code-->Pascal RTL--|
                           |-->SYS$PUT->SYS$QIOW-->terminal driver
Basic code--->Basic RTL---|

No difference.

$ type zm.bas
program zm

declare string s

print "XXX"
s = "YYY" + chr$(13) + chr$(10)
print s
print "ZZZ"

end program
$ bas zm
$ link zm
$ run zm
XXX
YYY
ZZZ
