Functions
=========
The 'FizzBuzz' example gave us an good overview.
== Arguments 'by reference'
We can also pass parameters by reference.
This enables us to change the variable with in the function.
[source,chapel]
./reference.lm
----
str sa( where:ref < str > ) {
print( "in SA ", where, "\n" )
where = "sa"
print( "in SA ", where, "\n" )
}
where: str = "global"
print( "in global ", where, "\n" )
sa( where )
print( "in global ", where, "\n" )
----
Compiling and running would give us:
----
in global global
in SA global
in SA sa
in global sa
