Hi,
How can I convert the scalar 'A' (or 'a') to 1, 'B' to 2 and so on?
Related: how do I get the true internal value for A, i.e. ascii value?
Thanks!
Joe

my %alpha_to_num;
@alpha_to_num{ A .. Z } = ( 1 .. 26 );
print $alpha_to_num{ A };

or if you do it often

No benefit to that, really. ord('A') is calculated at compile-time, not
run-time.
