Description
substr takes characters from the string, bigstring and concatentates them to from the
output, littlestring. The vector, charindex, determines the characters and their
order.

shown in the example, there is no requirement that the characters specified in charindex
be contiguous or non-repeated.
To find a specified character in a string use the function: index.
Example
alphabet = " abcdefghijklmnopqrstuvwxyz"
mantra = substr(alphabet,[14,22,1,19,22,13,6,20])?
