Message Operations
This chapter shows how to use the DL20 Offline Programmer to:
• Create new messages
• Edit existing messages
• Delete messages
• Copy messages
Messages created using the DL20 Offline Programmer are stored on disk or
in the DL20 subdirectory. Each message is stored in a separate file with the
name MSG####.DAT. The #### characters represent a message number
from 1 to 1022. For example:
MSG0001.DAT Message 1
MSG0002.DAT Message 2
MSG0003.DAT Message 3
.
.
.
MSG1021.DA T Message 1021
MSG1022.DA T Message 1022
Note: The first sixteen messages (1 – 16) store special DL20 messages.
When you edit and save an existing message, the original version of the
message is retained with the same file name but the .OLD extension. For
example, if you edit Message 20, the following two files reside on disk:
MSG0020.DA T new, edited file
MSG0020.OLD old, original file
If you prefer the old version of the message, delete the new message and
rename the old version. For example, to delete the edited version of Message
20 and retain the original version, type the commands below at DOS level.
C:\DL20>ERASE MSG0020.DAT [Enter]
C:\DL20>RENAME MSG0020.OLD MSG0020.DAT [Enter]

Message File Conversions
This chapter shows how to:
• Convert DL20 message files to an S Record File
• Convert an S Record File to DL20 message files
• View DL20 files on disk
It is recommended that you convert all DL20 files to an S Record file. The S
Record file stores all message files (MSG####.DAT) and configuration files
(IOFILE.DAT, PIOFILE.DAT, MSTRFILE.DAT) in a single file.
Downloading an S Record file to a DL20 or data recorder is more efficient
and faster then downloading individual files. You can then delete the
original .DAT files to save disk space.
To print DL20 message files or to modify the configuration files, you must
convert the S Record file back to the individual DL20 message files. The
files are converted with their original names.
