Progress Operators

The following list details initial information of some Progress Operators that can be used. Additional information is available at OpenEdge ABL Reference

Operator	Description	Usage
+	Adds two numeric expressions	expression + expression expression Any expression resulting in a numeric value
+	Joins two character string or expressions	expression + expression expression Any expression resulting in a character or string value
+	Adds a number days to a date	date + days date Any expression that results in a date days Any expression with an integer value
-	Subtracts a numeric expression from another	expression - expression expression Any expression resulting in a numeric value
-	Subtracts a number of days, or a date, from a date	date - days date - date date Any expression that results in a date days Any expression with an integer value
*	Multiplies two numeric expressions	expression * expression expression Any expression resulting in a numeric value
/	Divides one numeric expression by another numeric expression	expression / expression expression Any expression resulting in a numeric value
AND	Returns TRUE if each logical expression is true	expression AND expression expression Any expression resulting in a logical value (TRUE or FALSE)
EQ =	Returns a True value if two expressions are equal	expression EQ expression expression = expression expression A field name or expression. The data types on each side must be the same
GE >=	Returns a True value if the first expression is greater or equal to the second	expression GE expression expression >= expression expression A field name or expression. The data types on each side must be the same
GT >	Returns a True value if the first expression is greater than the second	expression GT expression expression > expression expression A field name or expression. The data types on each side must be the same
LE <=	Returns a True value if the first expression is less then or equal to the second	expression LE expression expression <= expression expression A field name or expression. The data types on each side must be the same
LT <	Returns a True value if the first expression is less than the second	expression LT expression expression < expression expression A field name or expression. The data types on each side must be the same
NE <>	Returns a TRUE value if two expression are not equal	expression NE expression expression <> expression expression A field name or expression. The data types on each side must be the same
NOT	Returns TRUE if the expression is false and FALSE if the expression is true	NOT expression expression Any expression resulting in a logical value (TRUE or FALSE)
OR	Returns a TRUE value if either of two logical expression are TRUE	expression OR expression expression Any expression resulting in a logical value (TRUE or FALSE)
