Bug ID: 153142
Summary: IsMissing needs a note about use in conditions (no
boolean short-circuit evaluation in Basic)
Product: LibreOffice
Version: unspecified
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: Documentation
Assignee: [email protected]
Reporter: [email protected]
CC: [email protected]
There is a recurring programming error in Basic, when IsMissing is combined by
a logical operator with a use of potentially absent variable, as in
> If Not IsAbsent(foo) And foo > bar Then ...
See e.g. code shown on the screenshot at
https://ask.libreoffice.org/t/messagebox-weird-response/86789
We need a comment on IsMissing help page, discussing that this must be
> If Not IsAbsent(foo) Then If foo > bar Then ...
