Figure 64. Module DVGCXAMD—Sample Message Module
In your message module:
� The macro name must be the name you gave to your copy of DVG$GMC.
� The value of SECTYPE must be CSECT.
� The value of SECTNAM must be the same as the name of the load
module.
8. Assemble your message module.
9. Link-edit your message module using the same load module name that you
specified for the SECTNAM operand.
Rules to Follow when Changing the Message Texts
� Do not use the character @ when changing messages. This character is used
by NetView FTP V2.2.1 MVS to indicate where in the message the variable
information is to be inserted.
� You can change the fixed portion of the text, even the length of the fixed
portion.
� You can change the relative positions of the variables. The number of variables,
however, must remain the same.
� All messages in the DVG$GMC macro must be written in uppercase letters.
� A variable or blank must appear every 38 bytes.
� A variable is denoted by the string &VP.nn, where nn is a 2-digit number. Generally
the numbers start with 01 and are incremented by 1.
� A variable must be preceded by a blank unless the variable is the first item in
the message.
� A variable must appear in the first 255 bytes.
� The variables referred to in a changed message must be the same as those
referred to in the original message.
� The value of a variable is set by the module that issues the message. You
cannot set the value of a variable.
