I've been unable to reference an array element within math mode within PGML. Here is a minimal example, with various things I have tried, none o which work:
for my $i (0..2)
{$a[$i] = random(2,8,1);}
BEGIN_PGML
[`[$a[0]]`]
[:[$a[0]]:]
[`[$a[[0]]]`]
[:[$a[[0]]]:]
END_PGML
{$a[$i] = random(2,8,1);}
BEGIN_PGML
[`[$a[0]]`]
[:[$a[0]]:]
[`[$a[[0]]]`]
[:[$a[[0]]]:]
END_PGML
Is it possible to reference perl array elements using PGML?
