			== Scope ==

			<code>call</code> can only execute functions that are ''visible in the scope of the <code>call</code> statement''.

			For example, executing the following ASH code will result in an error, because the <code>func_inside_bar()</code> function is not visible from within <code>foo()</code>:

			<syntaxhighlight lang="d" line highlight="3">
			void foo( string callback ) {
			// foo() cannot see func_inside_bar()
			call void callback( 123 );
			}

			void bar() {
			void func_inside_bar( int arg ) {
			print( arg );
			}
			foo( "func_inside_bar" );
			}

			bar(); // Error: Function 'func_inside_bar( int )' undefined.
			</syntaxhighlight>

			However, the following code will run successfully:

			<syntaxhighlight lang="d" line highlight="5">
			void foo( string callback ) {
			void func_inside_foo( int arg ) {
			print( arg );
			}
			call void callback( 123 );
			}

			void bar() {
			// Although bar() cannot see func_inside_foo(),
			// it can still pass its name to foo()
			foo( "func_inside_foo" );
			}

			bar(); // Prints "123"
			</syntaxhighlight>

Created page with 'Syntax: call [''type''] <identifier>( param, ... ); : ''type'' is an optional parameter which must match the return value of the function. If not specified, ''type'' defaul…'

New page

Syntax: call [''type''] <identifier>( param, ... );
: ''type'' is an optional parameter which must match the return value of the function. If not specified, ''type'' defaults to void.

For instance:
<div style="margin-bottom: 1em; border: dashed 1px green; padding: 1em; margin:0px 20px;"><syntaxhighlight>
int foo( int a, int b )
{
return a + b;
}

String a = "foo";

float c = call float a( 2, 3 );

print( "c = " + c );

a = "hello world";

call a( "print 1" );

print( "done" );
</syntaxhighlight></div>
will output the following to the CLI:
c = 5.0
hello world
done
