This example demonstrates the operation of the CGOTO command, which allows execution to continue at a position dynamically calculated at execution time, based on the value of an expression.

 
 10 CLS
 20 x = 3
 30 CGOTO x*100
 40 PRINT "really fails!": GOTO 20
 100 PRINT "fails!": GOTO 20
 200 PRINT "fails!": GOTO 20
 300 PRINT "success!": GOTO 20
