strLHS: Type: String
The first string .
strRHS: Type: String
The second string.

Return Value

Type: Long
This function returns a numeric value to indicate the order in which the strings should be sorted:

-1	LHS precedes RHS in the sort order.
0	LHS occurs in the same position as RHS in the sort order.
1	LHS follows RHS in the sort order.

Remarks

The StringCompare method takes into account:
- the setting of SetExact()
- the setting of VO13 of the main app
- the setting of Collation mode
This method respects the current setting of SetCollation():
- When the current collationmode is Clipper or Windows then a Unicode - Ansi conversions will be performed. The Clipper collation uses the current DOS codepage and the Windows collation the current Windows codepage.
- When the current collationmode is Unicode or Ordinal then the original strings will be compared.
