3.2.8 Functions function

$A[SCII]( expr )

produces an integer value as follows:

–1 if the value of expr is the empty string.

Otherwise, the decimal equivalent of the ASCII code of the leftmost character of the value of expr.

$A[SCII]( expr₁ , intexpr₂ )

is similar to $A(expr₁) except that it works with the intexpr₂th character of expr₁ instead of the first. Formally, $A(expr₁,intexpr₂) is defined to be $A($E(expr₁,intexpr₂)).
