If you are taking a look at OMEGAMON XE For z/OS V5.1 or OMEGAMON XE For CICS V5.1, one of the nice features of the new enhanced 3270 is the ability to support various screen sizes and formats.
When you use a commonly available emulator, such as PCOMM, you have a choice of various screen sizes (such as 24x80, 32x80, 43x80, etc). What size you may use is a matter of preference. For example, a good size to use in terms of ease of use combined with ease of readability for many users is 43x80. Or you may prefer a different size. You have the flexibility to specify it.
Here's a neat tip from my colleague Ernie Gilman. You can set the screen size up to as high as 62x160. Why would you do that? Well one reason is you can get more data on the screen at once without having to scroll the displays. Here's an example of what I'm talking about:
To get this screen size you need to do two things. First you need to configure your emulator to support a 62x160 session. You then need to logon to OMEGAMON using a different logmode (the required logomode is d4a32xx3). When logging on you can often pass the logmode option as part of the logon string (for example - logon applid(omappl) logmode(d4a32xx3).
You get more data on the screen. Try it out, you might like it.
