I need to update the VSAM file with the message entered by the user so I have chosen to do the task using REXX.
So first I wanted one screen where I ask user to mention the message to be added and VSAM file name. In order to achieve the same in REXX please I do need some guidance as I know some of the basics of REXX.

To REXX, the "screen" is the Terminal Monitor Program (TMP) standard input: running in the foreground, it's the TSO terminal. In the background, it's the SYSTSIN DD statement.
There is nothing more sophisticated built into REXX then its standard SAY/PULL functions. Here's an example:
/* REXX */
Say "Please enter a filename =>"
Say "You Entered "the_filename
Whenever I'm creating an application for use by TSO users in the foreground, I prefer to use ISPF panels, even if they're extremely simplistic, mainly because that's what most people are used to working with. It's also nice because they provide the control over the entire contents of the screen, and can easily provide features such as data checking, range checking, highlighting and emphasis, and many other features.
