Unable to add numbers at the beggining of my TNS entry in the TNSNames Editor (4236329)

Unable to add numbers at the beggining of my TNS entry in the TNSNames Editor

EXAMPLE:

Add the number 0 in front of the TNS entry:

0MYINSTANCE =
(DESCRIPTION=
(ADDRESS=
(COMMUNITY=######)
(PROTOCOL=TCP)
(HOST=####)
(PORT=####)
)
(CONNECT_DATA=
(GLOBAL_NAME=####)
(SID=####)
)
)

When pressing Validate or Save, the zero is removed.

Result:

MYINSTANCE =
(DESCRIPTION=
(ADDRESS=
(COMMUNITY=#####)
(PROTOCOL=TCP)
(HOST=####)
(PORT=####)
)
(CONNECT_DATA=
(GLOBAL_NAME=####)
(SID=####)
)
)

When typing in the value to the ADD Service window, the TNSNAMES Editor performs checks after the user clicks 'OK'. TNS_ NAMES entries cannot begin with a number so it removes this.

WORKAROUND:
Manually edit the tnsnames.ora file via Notepad.
