==== BALANCED ====

BALANCED is an external function that converts a string to 
uppercase for internal processing.

<code>
BALANCED(string)
</code>

==== Using BALANCED ====

The string will not be converted if unbalanced quotation 
marks exist.

=== string ===

String is the string to be converted to uppercase characters.  
If a nested string exists in string, it will not be 
converted.  If the conversion is not successful, the string 
value is cleared.  String will contain the converted string 
upon successful completion.

==== Values returned ====

BALANCED returns true and passes the converted string in 
string if the conversion was successful, otherwise false is 
returned and null is passed in string.  An unsuccessful 
conversion indicates unbalanced quotes.

==== Correct Use of BALANCED ====

  * The following code demonstrates different ways of using BALANCED

<code>
DECLARE FUNCTION BALANCED
DECLARE SUBROUTINE MSG

*A simple conversion

string = "101 Villa Lane"
flag = BALANCED(string)
IF flag THEN
    MSG("string = %1%|flag = %2%","","", string:@FM:flag)
END

* A nested string conversion
string = "'e.e.' Cummings"
flag = BALANCED(string)
IF flag THEN
    MSG("string = %1%|flag = %2%","","", string:@FM:flag)
END
