Understanding File Organization

This chapter:

defines program, program files, and data files

indicates how programs are stored and transferred

covers the use of EEPROMs and UVPROMs for program backup

As explained in the following sections, the program can reside in:

the Hand–Held Terminal

an SLC 500 processor

a memory module

the APS terminal

Notes on terminology: The term program used in Hand-Held Terminal
(HHT) displays is equivalent to the term processor file used in APS software
displays. These terms mean the collective program files and data files
created under a particular program or processor file.

Most of the operations you perform with the HHT involve the program and
the two components created with it: program files and data files.
