The SET1 command assigns a single value to a variable, option, relation, or dimension surrogate. When an object has one or more dimensions, the SET1 command assigns the value to the object cell that is in current status.
Since the SET1 command does not loop through a dimensioned object, you can use it in Assign trigger programs to assign a value to an object.
SET1 target-name = expression
The name of the target object where the data will be assigned and stored. For a list of analytic workspace objects that can be a target object, see Table 10-9, "Using Objects in Assignment Statements".
The source of the data values to be assigned to the object, see Table 10-9, "Using Objects in Assignment Statements"
For an example of using SET1, see Example 10-163, "Setting Values in an ASSIGN Trigger Program".
