Hi.
The evaluation of
1+2;storeA:%;1-2;storeB:%;[storeA,storeB];
with maxima (running in a shell on the LON-CAPA server)
gives, as expected, [3,-1]
But using
cas( 'maxima', "1+2;storeA:%;1-2;storeB:%;[storeA,storeB];" );
in LON-CAPA does not work properly.
(I would like to use such structures in a library project.)
In principle the maxima variable % works.
my @CHECK_IN = qw(
1+2;
1+2;%;
1+2;%;%;
1+2;store:%;%;
1+2;store:%;store;
);
my @CHECK_OUT = map { cas( 'maxima', $_ ) } @CHECK_IN;
Alle five entries of @CHECK_OUT should be 3. The first three examples
work properly in LON-CAPA, but the other two don't; both evaluations
seem to yield random integer numbers.
I have a workaround, but using % would be the much better solution.
Any idea?

<script type="loncapa/perl">
my @CHECK_IN = qw(
1+2;
1+2;%;
1+2;%;%;
1+2;store:%;%;
1+2;store:%;store;
);
my @CHECK_OUT = map { cas( 'maxima', $_ ) } @CHECK_IN;
our $out_str = join '<br />', @CHECK_OUT;
$out_str .= '<br />'
. cas( 'maxima', "1+2;storeA:%;1-2;storeB:%;[storeA,storeB];" );
</script>
