SAS/IML Studio provides the following different types of windows.
A program window is an editor for IMLPlus programs. For each program window, SAS/IML Studio creates a workspace. There is always a one-to-one correspondence between a program window and a workspace. It is not possible to have two program
windows share a single workspace, nor is it possible to have a single program window connected to more than one workspace.
Program windows provide the following features:
color coding of IMLPlus keywords, string literals, comments, and constants
automatic indention of program statements
drag-and-drop text editing
positioning the cursor at the source of a program error
following errors into SAS/IML modules
multilevel undo and redo
bookmarks
finding and replacing text
An error log window reports warnings and errors from analyses, and programming errors that occur when you run a program.
An output document window displays output from analyses, output from the SAS/IML PRINT statement, and output from programs
that you run. The output window supports the Microsoft rich text format (RTF), so you can paste graphical objects (including
SAS/IML Studio graphics) from the Windows clipboard into the output document.
A data view is a generic name for a data table or a plot. Data views that display common data are linked together, which means
that selections made in one view are displayed in all views of the same data.
An auxiliary input window is a secondary programming window that is linked to the main program window. The IMLPlus PAUSE statement
pauses the main program, creates an auxiliary input window, and waits until you click . You can use the auxiliary input window as a debugging tool or to prompt for user input.
For example, the following program prompts for user input:
pause "Enter starting value in x. Example: x=10;"; do while ( x > 0 ); print x; x = x - 1; end;
When this program is executed, the auxiliary input window appears with the PAUSE statement’s message displayed, as shown in Figure 34.1. You can then type the statement
x=10;
into the Input box, and click . IMLPlus executes the statement to create the matrix x
, and then resumes execution of the main program from the line following the PAUSE statement.
