OpenOffice Basic

OpenOffice Basic (formerly known as StarOffice Basic or StarBasic or OOoBasic) is a dialect of the programming language BASIC that originated with the StarOffice office suite and spread through OpenOffice.org and derivatives such as LibreOffice (where it is known as LibreOffice Basic). The language is a domain-specific programming language which specifically serves the OpenOffice application suite.

Example

Although OpenOffice Basic is similar to other dialects of BASIC, such as Microsoft's Visual Basic for Applications (VBA), the application programming interface (API) is very different, as the example below of a macro illustrates. While there is a much easier way to obtain the "paragraph count" document property, the example shows the fundamental methods for accessing each paragraph in a text document, sequentially.

Sub ParaCount
'
' Count number of paragraphs in a text document
'
    Dim Doc As Object, Enum As Object, TextEl As Object, Count As Long
    Doc = ThisComponent
' Is this a text document?
    If Not Doc.SupportsService("com.sun.star.text.TextDocument") Then
        MsgBox "This macro must be run from a text document", 64, "Error"
        Exit Sub
    End If
    Count = 0
' Examine each component - paragraph or table?
    Enum = Doc.Text.CreateEnumeration
    While Enum.HasMoreElements
        TextEl = Enum.NextElement
' Is the component a paragraph?
        If TextEl.SupportsService("com.sun.star.text.Paragraph") Then
            Count = Count + 1
        End If
    Wend
'Display result
    MsgBox Count, 0, "Paragraph Count"
End Sub
gollark: Can you backup calculator contents to a computer somehow?
gollark: So they generally ship with "exam mode" features which shut off whatever exam boards disallow, plus access to user programs.
gollark: Like I said, the main purpose of calculators is for exams.
gollark: Presumably because if people have low-level hardware access they could mess with the "exam mode" stuff.
gollark: IIRC when adding Python support they dropped the assembly-language-programming features.
