SYMPTOMS
If an array is declared twice in a COMMON or a COMMON SHARED statement, it does not give you an error while running in the QuickBasic environment. The error is correctly flagged at compile time with a "duplicate definition" error.
STATUS
Microsoft has confirmed this to be a bug in the QB.EXE shipped with QuickBasic Versions 4.00, 4.00b, and 4.50 and in the QB.EXE shipped with Microsoft Basic Compiler Versions 6.00 and 6.00b (buglist6.00, buglist6.00b). This problem was corrected in the QBX.EXE environment of Microsoft Basic Professional Development System (PDS) Version 7.00 for MS-DOS and MS OS/2 (fixlist7.00).
Code Examples
The following examples reproduce the problem:
'example 1
COMMON SHARED A$(),A$()
'example 2
COMMON SHARED A$()
COMMON SHARED A$()
'example 3
DIM A(200) AS DOUBLE
COMMON SHARED A() AS DOUBLE, B$, C$, A() AS DOUBLE
'example 4
COMMON SHARED A%(),
COMMON SHARED B#,C#,A%()
