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.
