DISPLAY Statement

displays fields in display windows

DISPLAY <group-spec group-options, group-spec group-options>;

The inputs to the DISPLAY statement are as follows:

group-spec

specifies a group. It can be specified as either a compound name of the form windowname.groupname or a window name followed by a group of the form window-name (field-specs), where field-specs is as defined for the WINDOW statement.

group-options

can be any of the following:

NOINPUT

displays the group with all fields protected so that no data can be entered in the fields.

REPEAT

repeats the group for each element of the matrices specified as field operands.

BELL

rings the bell, sounds the alarm, or causes the speaker in your workstation to beep when the window is displayed.

The DISPLAY statement directs IML to gather data into fields defined in the window for purposes of display, data entry, or menu selection. The DISPLAY statement always refers to a window that has been previously opened by a WINDOW statement. The statement is described completely in Chapter 13.

Following are several examples demonstrating the use of the DISPLAY statement:

  
    display; 
    display w(i); 
    display w ("BELL") bell; 
    display w.g1 noinput; 
    display w (i protect=yes 
               color="blue" 
               j color="yellow");
