LotusScript

See:

Basic   

Language type:

A - Application/Macro

Description:

LotusScript is a dialect of Basic used as the application extension and macro language for Lotus's line of office automation software. It has some object-oriented programming features and extensive application integration and interface facilities.
Data types available in LotusScript include integers, reals, strings, arrays, records, and objects. The language supports conventional procedural constructs with simple Basic-style syntax. The language is not strongly typed, but does do some type enforcement for objects.
LotusScript employs a high-level simplified event model to invoke subroutines and functions in response to user input and application activity.
LotusScript is included as part of the Lotus commercial products it serves to extend. Documentation for the language is available from Lotus's web site and elsewhere on-line.

Origin:

Lotus Development Corp, 1995.

Remarks:

LotusScript corresponds directly to Microsoft Visual Basic for Applications and Corel CorelScript: they are all dialects of Basic that allow users to write extensions and simple applications within large software products (e.g. word processors, groupware systems).
LotusScript can be divided into a core language and set of classes, and application-specific objects and classes associated with the embedding product. For example, a LotusScript program running under Lotus Notes 4.5 has a different set of pre-defined classes available to it than a program running in Lotus Freelance. Books and classes about the language seem to be mostly directed at Notes, because it is a popular product and because it is an environment in which extensions and specialized features are commonly written.
Compared with other dialects of Basic, LotusScript appears somewhat more verbose or sugared. This appearance is the result of the object-oriented features of the language, and the additional type information those features use.

Forall a In db.Agents
  If ( a.Owner = session.UserName ) Then
    Set agentArray(count) = a
    count = count + 1
    If (count > 10) Then 
       Exit Forall
    End If
  End If
End Forall

answer = Inputbox$( "You have " & count & " agents. Delete them?" )
If (answer = "y") Or (answer = "yes") Then
   Forall a in agentArray
        Call a.Remove
