RTVMSG Message Function

The Retrieve Message (RTVMSG) function specifies a process that retrieves message text. You can then use the message text to perform any number of processes such as moving a character string (or strings) from a database file into a field. You could also concatenate two discrete character strings from different fields and place them in the same work field or some other text field in another file.

The RTVMSG function is attached to a special CA 2E system file called *Messages.

Default logic:

• CA 2E implements the RTVMSG function via a high-level language program call to a CL program (Y2RVMGC).
• The RTVMSG function returns a message to the calling program (that is, the program that called the RTVMSG function). You would have to declare the field that is to receive the returned message data as an output parameter to the RTVMSG function.
