pause

Description

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.

Examples

function c=foo(b)
a=42+b
disp("Thanks to the pause, you can investigate if ''a'' has the right value");
disp("Value can be changed too if needed.");
pause
c=a+2
endfunction

foo(2)
