Hi Pete,
To be able to pass a word to your function and have the word set to the
object created in the function requires two changes to your code:
1. The argument must be declared using a lit-word! notation:
logo-factory: func [ 'name ] [ .... ]
note the tick in front of name, i.e. 'name
2. You must use the set function to assign the created object to the word
passed to the function, i.e.
set :name make object! [ ....]
The complete modified code follows:
logo-factory: func [
"Creates and returns a named logo object."
'name "The name of the object to be created."
][
set :name make object! [
type: "text"
text: ""
pict: #{}
file: ""
altt: ""
switch-type: func [
"Toggles the logo object's type between 'text' and 'pict'."
][
type: either type = "text" ["pict"]["text"]
]
]
]
>> logo-factory Logo1
>> print mold Logo1
make object! [
type: "text"
text: ""
pict: #{}
file: ""
altt: ""
switch-type: func [
{Toggles the logo object's type between 'text' and 'pict'.}
][
type: either type = "text" ["pict"] ["text"]
]
]
