Description
The COMPARE function compares two strings and returns a value indicating whether or not they are equal. The function takes the form:
COMPARE (expression1, expression2 {, justification})Where:
- expression1 is the first string for comparison
- expression2 is the second string for comparison
- justification specifies how the strings are to be compared.
- "L" indicates a left justified comparison.
- "R" indicates a right justified comparison.
The default is left justification.
The function returns one of the following values:
- -1 The first string is less than the second
- 0 The strings are equal
- 1 The first string is greater than the second
An example of use would be as:
0001 A = "XY999" 0002 B = "XY1000" 0003 R1 = COMPARE(A,B,"L") 0004 R2 = COMPARE(A,B,"R") 0005 CRT R1,R2
The code above displays 1 -1, which indicates that XY999 is greater than XY1000 in a left justified comparison and XY999 is less than XY1000 in a right justified comparison.
