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.DAT Message 1021

MSG1022.DAT 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.DAT 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]
