>=
 Greater than or equal--binary                   (Relational)
------------------------------------------------------------------------------
 Syntax

     <exp1> >= <exp2>

 Type

     Character, date, logical, memo, numeric

 Operands

     <exp1> and <exp2> are expressions of any data type to be
     compared.

 Description

     The greater than or equal to operator (>=) is a binary operator that
     compares two values of the same data type and returns true (.T.) if
     <exp1> is greater than or equal to <exp2>.

     .  Character:  The comparison is based on the underlying ASCII
        code.  ASCII codes for alphabetic characters are ascending (e.g., the
        code for "A" is 65 and the code for "Z" is 90).

     .  Date: Dates are compared according to the underlying date
        value.

     .  Logical: True (.T.) is greater than false (.F.).

     .  Memo: Treated the same as character.

     .  Numeric: Compared based on magnitude.

 Examples

     .  These examples illustrate how the greater than or equal
        operator (>=) behaves with different data types:

        // Character
        ? "Z" >= "A"             // Result: .T.

        ? "AZ" >= "A"            // Result: .T.
        ? "A" >= "AZ"            // Result: .F.

        // Date
        ? CTOD("12/12/88") >= ;
           CTOD("12/11/88")      // Result: .T.

        // Logical
        ? .T. >= .F.             // Result: .T.

        // Numeric
        ? 2 >= 1                 // Result: .T.
        ? 1 >= 2                 // Result: .F.
        ? 2 >= 2                 // Result: .T.
