Also using classes False and True rather than their instances false
and true is questionnable.
|test isFact|
test := Array new:5.
isFact := false.
test doWithIndex:[ :each :i | ((each isNil) & (isFact not))
ifTrue:[
test at:i put:'plain'.
isFact := true
]
].
This code find the first nil and replace it with 'plain', so it could
be as well:
| test isFact firstNilIndex |
test := Array new: 5.
firstNilIndex := test findFirst: [:each | each isNil].
isFact := firstNilIndex > 0.
isFact ifTrue: [test at: firstNilIndex put: 'plain'].
