   = assigns a dataset to a set variable

 

v1 = v2       where v1 v2 are set variables

v = set-expression

●  Operator = assigns a dataset to a set variable

Use the = to assign a set variable to the result of a set operation. You can also assign a set variable to another set variable.

 

Example 13.29.1

= EXAMPLE

The following example shows how to use the assign = operator.

 

Operation 13.29.1

= OPERATION

# aspl WS1
    (start ASPL loading the sample workspace WS1)

①  aspl> a12 = f& a1 a2
    (a12 is assigned the intersection of a1 a2)

②  aspl> v
    (print the set variables symbol table)

③  aspl> display a12
    (display a12)

④  aspl> j12 = a12
    (j12 is assigned to a12)

⑤  aspl> v
    (print the set variables symbol table)

⑥  aspl> ud12 = {f\ {fU a1 a2} {fU a2 a3}}
    (here is an example assigning an expression to a set variable)

⑦  aspl> v
    (print the set variables symbol table)
