The message table (the table that contains the message) is identified in the program property msgTablePrefix. For details on the table name, see DataTable part in EGL source format.
The value of minimumInputMsgKey is a string or literal that matches an entry of the first column in the message table.
If a numeric key is used with a message table that expects a character key, the number is converted to a character string. If a string literal is used with a message table that expects a numeric key, the value in the string must be a signed or unsigned integer.
