Belongs to Function Group: Arithmetic and Data Movement Operations
The MULTIPLY
statement is used to multiply two
operands. Depending on the syntax used, the result of the multiplication may be
stored in operand1
or
operand3
.
If a database field is used as the result field, the multiplication results in an update only to the internal value of the field as used within the program. The value for the field in the database remains unchanged.
For multiplications involving arrays, see also Rules for Arithmetic Assignments, Arithmetic Operations with Arrays (in the Programming Guide).
Two different structures are possible for this statement.
When Syntax 1 used, the result of the multiplication can be stored in operand1.
