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
