Bug ID: 143706
Summary: Missing Optional argument is not properly missing,
when ':=' syntax is used
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: BASIC
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
Consider this BASIC code:
' No Option VBASupport
Sub Foo(Optional x As Double, Optional y As Double)
MsgBox ismissing(x) & " " & ismissing(y)
End Sub
Sub Bar
Foo(y:=10)
End Sub
It produces "False False", instead of expected "True False"; and inspecting
value of x inside Foo gives 0.
In non-VBASupport mode, we should not initialize missing optional arguments;
the problem looks specific to the := argument value syntax, and e.g.
Foo(, 10)
produces expected "True False".
Tested with Version: 7.2.0.2 (x64) / LibreOffice Community
