==Definition==
'''INT''' Exists ( <'''INT''' processID|processType> )

Checks if a [[process]] is alive.

== Parameters ==
{|
| '''INT''' processID or processType || - The ID or Type of the process to be checked.
|}

== Returns ==
'''INT''' : The result of the check
{|
| 0 (false) || - The process with given processID is not alive or there are no processes alive of the given type.
|-
| 1 (true) || - The process with given processID is alive or there is at least one process alive of the given type.
|}

== Example ==
<pre>
Program example;
Begin

Proc();

if(exists(id))
say("I exist!");
end
if(exists(type main))
say("I exist!");
end
if(exists(0))
say("0 doesn't exist");
end
if(exists(type proc))
say("Proc exists!");
else
say("Proc doesn't exist!");
end

Loop
frame;
End
End

Process Proc()
Begin
Loop
frame;
End
End
</pre>
Used in example: [[Say]]()
