Definition

A local variable is a variable that is specific to a process in the same way as a private variable. However, unlike a private variable it is possible for other processes to use these local variables by means of the ProcessID. Local variables up to Fenix version 0.86 are not specific to a particular process like private variables but each process has the same set of local variables which are defined after global variables following the statement Local.

Note that in most versions of Fenix the first local variable to be defined is bugged and will cause the program to crash if used. To avoid this, the first local to be declared by the user should not be used, but instead be a garbage variable.

Example

Program example;
Const
    someconstantvariable;
Global
    int globalint;
    string globalstring;
    //etc...
Local
    int UNUSED; //this variable is not used as it is bugged
    //[insert local variables that you can use here]
Begin
    //rest of program...
End

In Fenix versions 0.86 and later, it is possible to assign processes specific local variables is the same way that local variables are assigned:

Process example_process()
Private
   //some private variables
Local
   //some local variables
Begin
   //rest of code...
End

NOTE: There is a restriction with local variables assigned like this in that they can only be used by processes called after the process where they are assigned.

There are also a number of predefined local variables which are listed below.
