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"
.
