Here is at least one crazy solution:

KEYBOARD "?'hello'{ENTER}" clear
KEYBOARD "resume{ENTER}"
susp
WAIT WINDOW "hello"

And to avoid "feature is not available" in the exe:

on error *      && old trick, though works but gives the error when building exe
KEYBOARD "?'hello'{ENTER}" clear
KEYBOARD "resume{ENTER}"
susp
WAIT WINDOW "hello"
on error
