As an ESL Customer, you cannot add messages, since the message definition is compiled into the ESL product, only the ESL Syndetic engineering department can add a message as part of a new release of ESL.

As an ESL Customer, you cannot delete messages, as there definitions are compiled into the ESL product. If a message was the deleted, the indexing information within the message text file would become corrupted, which would potentially cause the wrong message to be displayed.

The only part of the message record that can be altered by an ESL Client is the text of the message. The identifier, parameter count, parameter types and parameter order must remain unchanged, this includes the order of the parameter placeholders within the text of the message.

You can change the maximum length of a string parameter that is inserted, by changing the placeholder within the text, as follows:

"%.70s" is not an ESL binary file.

only allows 70 characters for the name of the file to be displayed, changing the value between the "%." and the "s" to 120 as below, allows a longer file name to be displayed.

"%.120s" is not an ESL binary file.

There can be as many ESL message text files as you require, however, only one version of the message text file will be available for the instance of the ESL Compiler (Eparse.exe) and the ESL Runtime (EslRun.exe). The version of the message text file will be determined by the ESLERR parameter within the ESL configuration file.
