Bug ID: 171441
Summary: REGRESSION Predefined identifiers when executing any
Basic function
Product: LibreOffice
Version: 26.2.1.2 release
Hardware: All
OS: All
Status: UNCONFIRMED
Severity: normal
Priority: medium
Component: BASIC
Assignee: [email protected]
Reporter: [email protected]
Description:
When starting any Basic macro, a number of variables are predefined and
preinitialized, apparently as Global or Public variables.
You can replace them with a Dim statement.
They don't generate an error when they are not declared before use while Option
Explicit is present.
I identified so far 6 of them: a, x, y, dialog, height, width.
Steps to Reproduce:
1. Create any new document => File + New + Text document
Open the Basic IDE => Tools + Macros + Edit Macros...
Browse to the module Module1 in your new document
2. Next code is present
REM ***** BASIC *****
Sub Main
End Sub
3. Put the variables a, x, y, dialog, height, width as watched variables in the
watch window
4. Put your cursor on the line
Sub Main
and press F8
Actual Results:
- a is an integer, value = 0
- x, y, height, width are longs, value = 0
- dialog is an object containing (after expansion) the skeleton of an instance
of the SFDialogs.SF_Dialog class module !?
Expected Results:
The watch window should not show any value for any identifier.
Reproducible: Always
User Profile Reset: Yes
Additional Info:
Other tests done:
Insert between Sub Main and End Sub
- a = 10
=> OK
- a = Array()
=> error "Object variable not set"
With Option Explicit
- a = 10
=> done, it should raise a "Variable not defined" error
All tests done on a fresh installation of
Version: 26.2.1.2 (X86_64)
