SALIERI Language - Workspace and Objects

In SALIERI, almost every piece of data is represented as an object. Each object has a name, a type and a value. All objects are stored in the workspace and arranged in lexicographical order according to their names (except for the internal (or built-in) functions). Object names always start with a letter or an underscore ("_"), followed by an arbitrary number of letters, digits, or underscores. Capital and small letters are considered to be different.

Creating, Modifying and Deleting Objects

An object is created by assigning a value to a previously unassigned (i.e., unused) name. The type of the object is implicitly defined by the type of the assigned value.

Syntax of assignments:
name := expression

name is a valid object name and expression is an arbitrary expression. If a value is assigned to an object which already exists, the old value is automatically replaced by the new one and the type is automatically adjusted.

Objects are deleted using the internal functions delete and deleteAll.

To determine the type of an object or wether a specific object exists in the current workspace, the internal functions type and exists are used.

See also: delete, deleteAll, type, exists.

Loading and Saving the Workspace

To save the current workspace, the internal functions save and sync can be used. While save saves the workspace contents to a specified file, sync makes a backup copy to the file SALIERI.WSP which is automatically loaded whenever SALIERI System is initialized.

The internal function load loads workspace files into the current workspace; when loading a workspace file with load, its contents are added to the current workspace; if objects in the workspace file already exist in the current workspace, these are assigned the values as defined in the file.
