One feature of the enhanced 3270 ui is the ability to scroll a display or subpanel from side to side. How often you may need to scroll will depend on such things as the amount of data to view and how many lines and columns you defined when you set up your 3270 emulator session.
When you scroll you can have certain information on the left portion of the display stay in view. This makes it easier to keep information in context as you scroll. You can control how many columns will remain as static and stay in the display. The STATICCOLS parameter controls how many columns will stay in view on the screen.
Below is an example of the STATICCOLS parameter as used in and OMEGAMON IMS display. You can see in the example below the position of the static column (after IMS Region Name). This is set by setting STATICCOLS to 1. If you wanted to keep more information on the left of the screen static (such as IMS ID and Region Type) the set STATICCOLS to 2 or 3.
