Bill,
By using a Global variable in your function you can return
multiple values. Here is an example from the AmiBroker user guide, VariableB is
the global variable.
Example 2: Using local and global keywords to override
default visibility rules:
VariableA = <FONT
color=#ff00ff>5; //
implict global variable
function<FONT
size=2> Test() { <FONT
color=#800000> local
VariableA; // explicit local variable with the
same identifier as global <FONT
size=2> global<FONT
color=#000000> VariableB; // explicit global variable
not defined earlier
<FONT
color=#008000> //
may be used to return more than one value from the function<FONT
size=2> VariableA = <FONT
color=#ff00ff>99;
VariableB = <FONT
color=#ff00ff>333; }
VariableB = 1;
// global variable<FONT
color=#000000> "Before function
call"; <FONT
color=#ff00ff>"VariableA = " +
VariableA; "VariableB = "<FONT
size=2> + VariableB; Test(); <FONT
color=#ff00ff>"After function call"<FONT
color=#000000>; "VariableA = "<FONT
color=#000000> + VariableA + " (not affected by
function call )";
"VariableB = " +
VariableB + " (affected by the function call
)"
At the end of the function we can see 'return' statement that is
used to return the result to the caller. Note that currently return statement
must be placed at the very end of the function.
It is also possible to write a procedure (a function that
returns nothing (void))
