"All spreadsheets had been case insensitive ever since. " - I don't 
understand this.

The OpenFormula specification says that comparisons are case sensitive 
unless HOST-CASE-SENSITIVEisfalse.

>>>


     6.4.7Infix Operator "="

Summary:Report if two values are equal

Syntax:ScalarLeft =ScalarRight

Returns:Logical

Constraints:None

Semantics:Returns TRUE if two values are equal. If the values differ in 
type, return FALSE. If the values are both Number, return TRUE if they 
are considered equal, else return FALSE. If they are both Text, return 
TRUE if the two values match, else return FALSE. For Text values, if the 
calculation settingHOST-CASE-SENSITIVEisfalse, text is compared but 
characters differencing only in case are considered equal. If they are 
both Logicals, return TRUE if they are identical, else return FALSE. 
Error valuescannotbe compared to a constant Error value to determine if 
that is the same Error value.
