Scripting syntax
Before you create a script, make sure you understand the statement and syntax requirements.
Syntax overview
A script file can be written using any text editor (for example, WordPad, NotePad). A script file
consists of an unlimited number of statements that consist of macros (i.e., commands), work variables,
and comments. The first executable statement in a script file must be the Start macro, and the last
statement must be the End macro. Each line in a script file cannot exceed 320 bytes. A leading
blank is ignored, and a leading tab character (0x09) is converted to a space (0x20). A tab
character (0x09) within a string is not converted to a space.
Each script file should contain all five script statements (see Table 47 (page 103) and Table 48 (page
103)):
• A comment statement, including a short preface for the script: purpose, author, usage,
description, operation, creation date, update date, and any reminder notes to the author. The
comment statement is a non-execution statement. A comment statement begins with “//” and
contains text (any character string) without any commands. Do not use the “//” symbol
anywhere else in a script file, only at the beginning of a comment statement.
• A macro statement. The macro statement is an execution statement. Only one macro instruction
can be set per line, and a macro can span more than one line.
• A work variable statement. The work variable statement is also an execution statement. Only
one work variable statement can be set per line, and a work variable statement cannot span
more than one line.
• A blank statement (Table 47 (page 103)). The blank statement is a non-execution statement.
An empty statement (Table 47 (page 103)). The empty statement is a non-execution statement.
