chars is the 95 character list (excuse the wrap):
The search function looks in a list of the 95 printable ASCII characters from SPACE to ~ inclusive and returns the position of the characters "2", "3", "4" respectively as 18, 19, 20 (starting from the SPACE at position 0).
charbits is a nested vector of these same 96 characters defined as 7 row x 5 col bit maps.
When I run this routine the output is:
I know the charbits vector works because if I substitute , ,  for [idx] then I get the generated bitmaps.
My question is: How do I de-vector the output from the search line so that I have numbers instead of vectors.
