General
Avoid repeated scripts – Global Procedures.
Use ‘$region:<BlockName> to organize procedures
in the Global Procedures dialog
When applicable, use ‘On Error Resume Next’ and
‘On Error Goto 0’ in scripts
Make sure that when using $DBCursorOpen() or
$DBCursorOpenSQL(), call $DBCursorClose() to avoid
memory leaking.
