Thanks, Eric. Indeed -- a compiler logic bug. The two lines were being
connected, just as you surmised. It was introduced when Jmol's code became
free-form (like Java and JavaScript) -- believe it or not, back in Jmol
11.7.42:
x = 3
+ 10 +
5
print x
18
That continuation applies to only three commands:
x = ....
print ...
log ...
and the compiler wasn't distinguishing
x = ...
from
set x ....
in this particular instant and so thought it was still "in math mode". You
probably hit the only possible case where % (the only binary math operator
that can appear at the end of a line) appears at the end of a set command.
Wow! I certainly missed that.
That's fixed for 12.1.9 and 12.0.11. You can check here:
http://chemapps.stolaf.edu/jmol/docs/examples-12/Jmol-12.zip
The temporary work-around is to add a semicolon after that particular
statement:
set echo ename1 20% 50%;
font echo 25 sans bold
color echo yellow
echo Hello
Sorry about that!
Bob
ps -- By the way, if you have any line that uses ( ) or { } in the standard
way, you can continue to the next line anywhere between the open and close
of those now:
select (
ala
|| gly
)
