pause - pause mode, invoke keyboard
Switch to the pause mode; inserted in the code of a function, pause interrupts the execution of the function: one receives a prompt symbol which indicates the level of the pause (e.g. -1-> ). The user is then in a new workspace in which all the lower-level variables (and in particular all the variable of the function) are available. To return to the calling workspace enter "return"
In this mode, [...]=return(...) returns the variables of the argument (...) to the calling workspace with names in the output [...] . Otherwise, the lower-level variables are protected and cannot be modified.
The pause is extremely useful for debugging purposes.
This mode is killed by the command "abort" .
