Can you extract values from inside a procedure.

[chimerix]

What is it you are trying to achieve?
I need to extract variable values from inside a prodecurde or proccess into another.


What is the problem you are having?
I have no idea what to do.

Describe what you have tried to solve this problem
I tried to use the variable value into another procedure but its not working.

Please specify what version of Turing you are using
4.1.1

you should declare them as global variables (outside of a procedure at the top of your program), that way you can access them in any procedure or process

Turing:

var x : int procedure one()       x := 5  %now x is 5 end one procedure two()      one()      put x    % output will be 5      x := 10 %now x is 10 end two

Sounds like you might want to turn your procedures into functions.

Global variables are typically a bad idea, though it's difficult to discuss a good design, without knowing more about your code.

Also, processes are typically a very bad idea, as they are complex, not very well understood, introduce certain types of problems, and make it more difficult to figure out exactly what is going on in your code. Processes + Global variables are simply a terrible idea.

It could be a fun way to learn about the Readers-writers problem, though I'm not sure if Turing would have Semaphores or if something similar could be created from scratch.

my mistake, i forgot how random they are in turing and that would be a deadly combination, i never used them anyways after i read this: http://compsci.ca/v3/viewtopic.php?t=7842. what are you using a process for? you can probably avoid them all together, but you post didnt post any code or much info
