3-12 Expressions and Operators
String Operators Two operators in the module can manipulate STRINGS. These operators are ASC(
) and CHR( ).
ASC([expr])
Use the ASC operator to return the integer value of the ASCII character placed in
the parentheses.

The decimal representation for the ASCII character A is 65. The decimal
representation for the ASCII character a is 97. However, the module capitalizes all
ASCII characters not contained within quotation marks. Similarly, special ASCII
characters whose decimal value is greater than 127 should not be used.
In addition, you can evaluate individual characters in a defined ASCII string with
the ASC operator.
