the multiline display format. If the object display requires more than one display line, the display
starts at coordinate #x #y, and continues down the display either to the end of the object or the
bottom of the display. NOTE: DISPXY is not useful for displaying GROBs.
The object displayed by DISPXY persists in the display only until the keyboard is ready for
input. The FREEZE command can be used to cause the object to persist in the display until a
key is pressed.

DO
Type:
Command
Description: DO Indefinite Loop Structure Command: Starts DO...UNTIL...END indefinite loop structure.
DO ... UNTIL ... END executes a loop repeatedly until a test returns a true (nonzero) result. Since
the test clause is executed after the loop clause, the loop is always executed at least once. The syntax
is: DO loop-clause UNTIL test-clause END
DO starts execution of the loop clause. UNTIL ends the loop clause and begins the test clause.
The test clause must return a test result to the stack. END removes the test result from the stack.
If its value is zero, the loop clause is executed again; otherwise execution resumes following
END.
