●  Operator pop pops the last result from the answer stack into a set variable

Use the operator pop to pop the answer stack. If the operator is followed by a variable name then the operation will pop the top of the stack and assign it to the set variable.

 

Example 3.8.1

pop EXAMPLE

In this example we start ASPL loading the sample workspace WS1, then we issue a set operation to intersect two set variables. We pop the answer stack into a set variable.
