Manipulating Files Section 5-2
Symbol Tables, Comment Files, Program Index Files (CS1-H/CJ1-H, CJ1M, CS1D CPU Units with Unit
Version 3.0 or Later Only)
Note The backup, restore, and comparison operations in the above table are per-
formed only for files contained in comment memory.
Verifying Backup Operations with Indicators
The status of the Memory Card Power (MCPWR) indicator shows whether a
simple backup operation has been completed normally or not.
File name and
extension
Contents Backup from
CPU Unit to
Memory Card

Restore from
Memory Card
to CPU Unit
Comparing

restoring data
CPU Unit CS1-H, CJ1-H, CJ1M, or CS1D CPU Unit with unit version 3.0 only
BKUPSYM.SYM Symbol table files Yes (writes if
CPU Unit com-
ment memory
contains files)
Yes (reads to
CPU Unit com-
ment memory if
Memory Card
contains files)
Yes (compares
with files con-
tained in CPU
Unit’s comment
memory)
These files are
not absolutely
required in the
Memory Card.
