DEFAULT

SELECT n
CASE 3; ...
CASE >3; ...
CASE 2 TO 5; ...
DEFAULT; ...
ENDSELECT



The DEFAULT keyword is a special (OPTIONAL) type of CASE statement. If none of the CASE statements within a SELECT block match n then the code-block under the DEFAULT statement (if a DEFAULT case exists) will be run.

Example:
 
// SELECT CASE DEFAULT ENDSELECT

FOR n=0 TO 10

PRINT "n="+n, 100, 100

  SELECT n
  CASE 7
   PRINT "n="+n+": CASE 7", 0, n*10
  CASE >9
   PRINT "n="+n+": CASE >9", 0, n*10
  CASE >3
   PRINT "n="+n+": CASE >3", 0, n*10
  CASE 3 TO 8
   PRINT "n="+n+": CASE 3 TO 8", 0, n*10
  DEFAULT
   PRINT "n="+n+": DEFAULT", 0, n*10
 ENDSELECT
NEXT
SHOWSCREEN
MOUSEWAIT



Output:
n=0: DEFAULT
n=1: DEFAULT
n=2: DEFAULT
n=3: CASE 3 TO 8
n=4: CASE >3
n=5: CASE >3
n=6: CASE >3
n=7: CASE 7
n=8: CASE >3
n=9: CASE >3
n=10: CASE >9
