2.2.7.1 $ASCII

$A[SCII] ( expr )

See 2.3 for the definition of expr.

This form produces an integer value as follows:

  1. –1 if the value of expr is the empty string.
  2. Otherwise, an integer n associated with the leftmost character of the value of expr, such that $A($C(n)) = n.

$A[SCII] ( expr , intexpr )

See 2.3 for the definition of expr. See 2.2.4.1 for the definition of intexpr.

This form is similar to $A(expr) except that it works with the intexprth character of expr instead of the first. Formally, $A(expr,intexpr) is defined to be $A($E(expr,intexpr)).
