2 The Language

QddbScript has a format similar to HTML[2], but it uses square brackets ([]) instead of <> to denote the beginning and end of a command. All command names are case insensitive. Some QddbScript commands such as frame require end markers:

    [frame]
    [end frame]

Other commands, such as entry, require certain options for proper operation of the script. Unrecognized or invalid options are always ignored, as well as any part of a line after a pound sign (#) not within a string. Semicolons that are not within a string are also ignored, so you can freely place them anywhere you like to add clarity to your script.

The current general commands and their options are listed in Table 2.1. Strings may be one of the following forms:

A[A-Za-z0-9\.]	Alphanumeric strings (periods ok) starting with alpha
``any valid string \verb+\"+ goes here''	Double quoted string
{any valid string } goes here}	String within curly braces

Table 2.1: QddbScript commands and options

The options attr, relief, and side require certain values. attr requires a valid attribute name for the Qddb schema (such as Items.Qty). relief must be one of flat, raised, sunken, or groove. The default relief is flat. side must be one of left, right, top, or bottom. The default side is top for frames and left for entries, text, labels, and radiobuttons.
