How a program can call to itself without using function.

I have to execute a program which is calling itself if an particular condition satisfies, without making that program as function.

Could you add some context/details as to why a program would need to call itself, and why you want to do this without making the program a function.

Code, which calls itself controlled by a condition without being a function, sounds as a while loop.

It is possible to have a script call itself. For example have this in test3.m:

clc;
d = dbstack;
timesCalled = length(d)
if timesCalled > 495
  return;  % Prevent max recursion error.
end
fprintf('Current time = %s\nType control-C to exit\n', datestr(now));
test3

Though I'm not sure how advisable this is.
