Macro Programming Language 163
FXDeko User’s Guide
The following macro creates, then runs the macros “boy” and “girl” as
subroutines.
command boy
type "It’s a boy!"
end
command girl
type "It’s a girl"
end
if $name == "Amy"
girl
elseif $name == "Meg"
girl
elseif $name == "Mickey"
boy
end
The subroutines “boy” and “girl” are local to this macro. When the macro ends,
the subroutines, like the variables, vanish.
R ETURN V ALUES
The return command directs FXDeko to stop the current macro or subroutine
and return the value of its expression parameter to the macro that called it.
return [expression=]
For example, you might have a simple command called test that returns 1 if
successful, or 0 if not:
command test
if $name == "Amy"
return 1
else
return 0
end
The subroutine test can then be called from another macro:
$result = test
if $result == 1
type "It’s a girl"
end
Here are a few examples of FXDeko commands that return values:
$squareroot = sqrt 4.
sqrt returns the real value 2.
$test = file_open "moon over miami"
file_open returns 1 if FXDeko successfully opens "moon over miami", or 2 if
not.
$color = rgb 0 0 100
The rgb command creates and returns a color object that is then assigned to the
variable $color.
