The CSI and SS3 characters are shown for your information only. You need not check for their
presence because the remaining characters are unique and need no qualification.
The definition and value of the CSI and SS3 characters used in Table 11–2 follow:
01 SS3X
01 SS3 REDEFINES SS3X
01 CSIX
01 CSI REDEFINES CSIX
Figure 11–10 and Figure 11–11 show the Compaq COBOL control keys for various
terminals. The shaded keys correspond to the keypad names in Table 11–2, which
lists the characters returned to the application program.
In Figure 11–11, your keyboard may differ slightly, but the Compaq
COBOL control keys are as pictured.
Example 11–10 shows you how to use the CONTROL KEY phrase to handle
arrow keys, program function keys, keypad keys, Ctrl/Z, Tab, and Return.
When you use this phrase, you allow program function keys and arrow keys, as
well as Return and Tab keys, to terminate input. This phrase also permits you to
use those keys to move the cursor and to make menu selections without typing
any data on the screen.
