Example

 $ A = "23"
 $ B = F$INTEGER("-9" + A)
 $ SHOW SYMBOL B
   B = -923 Hex=FFFFFC65 Octal=176145

     This example shows how to use the F$INTEGER function to equate
     a symbol to the integer value returned by the function. In the
     example, the F$INTEGER function returns the integer equivalent
     of the string expression ("-9" + A). First, the F$INTEGER
     function evaluates the string expression by concatenating
     the string literal "-9" with the string literal "23". Note
     that the value of the symbol A is substituted automatically
     in a string expression. Also note that the plus sign (+) is a
     string concatenation operator because both arguments are string
     literals.

     After the string expression is evaluated, the F$INTEGER
     function converts the resulting character string ("-923") to
     an integer, and returns the value -923. This integer value is
     assigned to the symbol B.
