In CATIA V4, DS had provided an interrupt command to kill the
execution of commands.
In CATIA V5, there is no such command. hence the users have no
option but to terminate the process if the processing takes more
time and users loses the patience.
I found that on AIx sometimes using CTRl + X keys on the console
running the CATIA kills the execution of the current executing
command and not CATIA. but this is not always true. So, Take care
before you go for this....
