2-6 Programming with SCRIPTS
2.4 Using SCSI SCRIPTS
The following section of the chapter describes various aspects of SCSI
SCRIPTS.
2.4.1 SCRIPTS Data Sizes
Table 2.2 describes SCSI SCRIPTS data sizes.
2.4.2 SCSI SCRIPTS Language Elements
Table 2.3 describes the SCSI SCRIPTS language elements.
Table 2.2 Data Sizes
Address a 32-bit number
Value a 32-bit number
Count a 24-bit number
Data an 8-bit number
ID a 4-bit encoded SCSI ID

Term Definition
name A name is a string of one or more consecutive characters. It may consist of letters,
numbers, underscores, and dollar signs, but must begin with an alphabetic character.
When used for labels, externals, and variables in the relative data area, names are
passed on to the host development system and are subject to the host's syntactic
restrictions. Names cannot be reserved words in the host language. For example,
Turbo C, which is used as the host development system for NASM, does not allow names
to begin with a digit or to contain a dollar sign ($). Therefore, the SCSI SCRIPTS writer
for DOS and Turbo C should avoid names of this form.
label A label is a name followed by a colon. Labels are symbolic addresses that can be used
as transfer control destination points, such as jump or call destinations. Labels are case
sensitive.
comment Comments are used to notate the SCRIPTS. They are optional and are ignored by the
compiler. Comments begin with a semicolon and continue to the end of a line.
