The following creates a simple check box:
DISPLAY CHECK-BOX, TITLE "Option &1",
HANDLE IN CHECK-BOX-1.
Here is the Screen Section equivalent:
03 CHECK-BOX, "Option &1".
In this example, the check box starts out with a check mark in it:
DISPLAY CHECK-BOX "Option &2", VALUE 1,
HANDLE IN CHECK-BOX-2.
It is common in Screen Section entries to assign a VALUE data item to the box so that you can set and test the check box:
03 CHECK-BOX, "Option &3", USING OPTION-3-FLAG.
Here is a check box that can be dynamically disabled (grayed-out):
03 CHECK-BOX, "Option &4", USING OPTION-4-FLAG,
ENABLED = BOX-4-ENABLED-FLAG.
