This function is called when a call to the built-in function {\em
ascii} is to be processed.
If the last pushed value is a string, then the return register
is set to the integer (ASCII number) representation of the first
character in the string. Otherwise, the stacked argument is taken
as an {\em int} and the return register is set to the
character-to-string representation.
