Type: Byte
The first list of bytes.
aRHS
Type: Byte
The second list of bytes.
nLen

Return Value

Type: Long

Remarks
This method works on BYTE arrays and is used by the RDD system.
This method respects the current setting of SetCollation():
- When the current collationmode is Clipper or Windows then no Ansi - Unicode conversions will be done.The comparisons will be done on the byte arrays.
- When the current collationmode is Unicode or Ordinal then the byte arrays will be converted to Unicode before the comparison is executed.
