Using Commands in Report Generation
This chapter describes the commands which make up the report generation
programming language. After reading this chapter, you should be able to:
Use report generation commands directly in the command mode
Use report generation commands within procedures to manipulate data
As we described in chapter 5, the report generation programming language
uses commands to tell the 1775-S4B scanner what to do. Report generation
supports two types of commands:
Direct commands which you enter individually in the command mode
for immediate execution
Indirect commands which you enter into a procedure in sequence with
the other commands for later execution
We describe 1775-S4B scanner commands for report generation in the
following sections.
Report generation does not limit you to using commands directly from the
command mode or indirectly within a procedure. We present the
commands under the topic in which they are normally used. Some
commands have applications for both topics so we discuss them under both
topics. However, you can use any command from the command mode or
within a procedure to meet your needs.
A direct command tells the 1775-S4B scanner to perform the command
immediately after you enter it. You enter a direct command from the data
terminal keyboard whenever the 1775-S4B scanner is in the command
mode, indicated by the S4B> prompt. Direct commands include:
Print
