Use count commands to check whether respondents have the same value for all
variables

I infer from Paul's response that a "straightliner" is someone with the same value for a bunch of variables.  If that is correct, the SD of those variables will be equal to zero.  So...

COMPUTE StraightLiner = SD( insert your variable list )  EQ 0.

It would be nice if OP's followed up on their questions when asked for clarification/definitions.
What is the definition of a straightliner?
I doubt that any respondents just give a straight response all the way through a survey/qnaire.
What if there are 20 questions and 19 of them elicit the same response?
I'd say that counts as a 'straightliner'.
Maybe something that measures and counts sequence lengths?
Maybe a moving variance?
I not going to bother with any of that without something more specific.
