Before using this manual, you should understand
the information in the IBM 5110 APL Introduction,
SA21-9301, especially:
• How to enter data from the keyboard
• How APL functions work with one or two
arguments
• How to create your own user-defined functions
using the built-in APL functions
This manual is intended to be used with the IBM
5110 APL Reference Manual, SA21-9303; that is,
this manual gives you information about using the
5110 system with the APL language for
information processing. The major topics are:
• Computer concepts for data processsing
(Chapter 1)
• An approach to breaking your application into
small parts to make programming easier
(Chapter 2)
• Elements of the APL language and example APL
user--defined functions used for information
processing (Chapter 3)
• Controlling the information in the active
workspace (Chapter 4)
• Using uppercase and lowercase characters,
scrolling the display screen up or down, and

user-defined functions used for formatting
reports (Chapter 9)

applications (Chapter 10)
• Determining what to do when your program
doesn't work (Chapter 11)
This manual is not intended to give you a
complete description of the syntax and rules
required for each APL command, function, or
variable; you must use the 5110 APL Reference
Manual for this information.
This manual does not need to be read chapter by
chapter. Instead, you can read the appropriate
chapters as required. For example, you might read
Chapter 9, Printer Control when you need to
format a report.
