3.0 Creating Data

This section describes how to use a script to arrange data on a CD.

DOS files containing scripts are called script files. Script files are referenced and

processed by the preprocessing programs (

VCDPRE.EXE, VCDBUILD.EXE, and

VCDUTL.EXE) as well as the VCD emulator. Scripts are collections of lines described

in alphanumeric characters. Lines are composed of keywords with zero or more

parameters. Different keywords require different parameters. When keywords have

multiple parameters, the parameters have a set order. Moreover, the sequence of

lines cannot be arranged arbitrarily in the script; they have a set position pre-deter-

mined by the keyword.

Section 3.1 explains how to use commands to configure the disc image. Section 3.2

describes the line format and explains where they are placed within the script.

Tables 1 through 5 list the keywords and their parameters.

3.1 Determining Disk Configuration

How to Use Define

Define A B ; B character string is defined as A.

If this is used, A should be enclosed by [ ].

File [A] ; This becomes File B.

File A ; Remains File A.

Define is received no matter which line of the script it is described in, and

this becomes effective with respect to the script beyond the defined location.

How to Use Include

Include “a.scr” ; include “a.scr” in this location.

Include is processed no matter which line of the script it is described in.

However,

Include becomes effective up to two hierarchies (from within the

file performing

Include until the place where Include is performed).
