Hi, I just want to know if there's any way to catch an exception when trying to
evaluate an unbound variable using evalhook?


Thanks,

Do you realize that you are responsible for making this organization a cost,

Establish a handler for the UNBOUND-VARIABLE condition, just as you would
outside EVALHOOK.
