The dynamic nature of IML gives you the ability to create windows on your display for full-screen data entry or menuing. By using the WINDOW statement , you can define a window, its fields, and its attributes. By using the DISPLAY statement , you can display a window and await data entry.
These statements are similar in form and function to the corresponding statements in the SAS DATA step. The specification of fields in the WINDOW statement and DISPLAY statement are similar to the specifications used in the INPUT statement . By using these statements you can write applications that behave similarly to other full-screen facilities in the SAS System, such as the BUILD procedure in SAS/AF software and the FSEDIT procedure in SAS/FSP software.
